SCENARIO 'Re-engineering the human ...' Experts from a biometric engineering team predict that bionic technology will give us longer, healthier lives in the future. 'Re-engineering the human', explores some remarkable breakthroughs in the design of prosthetic limbs, artificial organs, bones and even blood cells. Bionic limbs with machine intelligence can now sense their environment and predict a user's intentions. Smarter, stronger, speedier robotics will someday enhance the power of the able-bodied. A new prosthetic arm actually composed of a swarm of robots, each with a detachable segment housing a processor that works in concert with the others, is bringing new hope to many people.

still necessary in an application? Give TWO reasons for your answer. (3) 4.7 How will 'interrupts' work together with 'plug and play', so that a newly inserted

device can immediately be available to the user? (2) [30]



QUESTION 5 5.1 Twitter can bring about a transformation in society. Either agree or disagree with

this statement by providing TWO arguments. Justify each argument. (4)

5.2 The biometric engineering team is also involved in nature conservation. With the plight of the rhino at present, the staff decided to start a rhino watch as they have a herd of rhino in the conservancy. Employees of the company go on game walks over weekends and tweet the location of the rhinos and of any other interesting sightings.

5.2.1 Suggest a hash tag for the tweets. (1)

5.2.2 Do you think it would be a good idea to tweet the locations of the rhino? Justify your answer. (2)

QUESTION 6 The biometric engineering team must deal with aspects of sourcing equipment and obtaining quotations to set up their IT infrastructure. The first task is to create a database to hold the quotations (cost estimate) that will be submitted for supplying equipment. One of the task team members has set up the database shown below. For each item a minimum of three quotes is required. Some companies will provide more than one quotation (cost estimation). Relationships: • One-to-one: Each company has its own unique code and its own name, address and email. • One-to-many: Each company can provide more than one quotation per day. • Many-to-many: Quotations can have many items on it and items can appear on many

different quotations. Figure 6.1 Quotes

Field Name Data Type Description CompanyCode Text The first 5 letters of the company name followed by a sequence number CompanyName Text The name of the company CompanyAddress Text The address of the company CompanyEmail Text The email address of the company ItemCode Text Unique code for each item ItemDescription Text Description of the item ItemQuantity Text Number of items required ItemCost Text Cost of one item QuoteNo Text Unique number for each quote 6.1 Explain the purpose of a primary key in a database table. (2) 6.2 There are several problems with the design of this database. The steps below are

part of the process of solving the design problems.

6.2.1 All the data types were declared as text. Indicate TWO fields which should not be of a text type and indicate the appropriate data type for EACH of the fields you have identified. (4)

6.2.2 Considering that many companies have multiple quotations (cost estimations), what is the most obvious weakness of the Quotes table design with regard to capturing data on a quotation? You MUST explain your reasoning. (2)

6.2.3 A poorly designed database can lead to errors whilst doing normal, everyday database maintenance tasks. These errors are often referred to as 'anomalies'. Name THREE of the anomalies that can result from a badly designed database. (3)

6.2.4 The given table actually contains information on at least TWO separate

groups or categories of data. Normalise the database up to 3NF (Third Normal Form). Write the answer as a set of relations. You MUST show the following:

• The fields that each of the new tables will contain. (3) • The primary key of each table. (3) • The foreign keys and the tables that will contain the foreign keys needed to establish relationships/links between the tables. (3)



6.3 Part of a good database design is anticipating and preventing errors when entering data. Consider the data that can be captured about the quote. The task team have decided that they will not accept quotes for less than 100 units or more than 5 000 units.

6.3.1 What is the technique that can be used to ensure that data falls within a

predetermined range? (1) 6.3.2 Write out the rule you would use to ensure that the number of units entered

will not be outside the predetermined range. Use the field names from Figure 6.1. (2)

[23]



QUESTION 7 The biometric engineering team wants to write a little computer game quiz to teach facts about the rhino. In the game 'To Save the Rhino', ten questions must be correctly answered in thirty seconds. If correctly answered you get another rhino, if not, you lose a rhino. The questions will be aimed at recording correct facts about rhinos, (e.g. rhino horn is NOT an effective aphrodisiac or a cure for cancer, etc.) and teaching other facts about rhinos. There are TWO types of questions: TRUE or FALSE and MULTIPLE CHOICE with THREE options. The questions and correct answers are stored in a text file. Below are the class diagrams for each type of question:

QuesOb QuesTF QuesMultChoice

− question:String − question:String

− TF:boolean

− question:String

− ans:String

− a, b, c:String

7.1 The above classes could be simplified using inheritance. Draw the class diagrams,

clearly showing inheritance, and remove any unnecessary fields or methods. (3)

7.2 Give TWO advantages of inheritance. (2)

7.3 What does polymorphism mean? (2)

7.4 Parameters are fundamental to programming. Describe how the following concepts are related:

7.4.1 Formal parameters (2) 7.4.2 Arguments (2)

7.5 Problem: Input and validation of a (20) digit number. • The number will be valid if, and only if, the twentieth digit (20th) is equal to the

remainder of the sum of the first nineteen (19) digits divided by 20. • The program should print a suitable message informing the user whether the number is valid or invalid.

7.5.1 Declare any variable(s) necessary to store the above 20 digit number. (2) 7.5.2 Hence, using the variables (data structure) declared in Question 7.5.1, write

the algorithm that will allow for the input and validation of a (20) digit number. (7)

program must make sensible use of methods and parameters. 3. This paper is divided into two sections. All candidates must answer both sections. 4. This paper is set in programming terms that are not specific to any particular programming

language (Java/Delphi) or database (Access/MySQL). 5. Make sure that you answer the questions in the manner described because marks will be

awarded for your solution according to the specifications that are given in the question. 6. Only answer what is asked in each question. For example, if the question does not ask for

data validation, then no marks are awarded for it, and therefore no code needs to be written. 7. If you cannot get a section of code to work, comment it out so that it will not be executed

and so that you can continue with the examination. If possible, try to explain the error to aid the marker.

8. When accessing files from within your code, DO NOT use full path names of the file, as

this will create problems when the program is marked on a computer other than the one you are writing on. Merely refer to the files using their names and extensions, where necessary.

9. Your programs must be coded in such a way that they will work with any data and not just

the sample data supplied or any data extracts that appear in the question paper. You are advised to look at the supplied data files carefully.

10. Make sure that routines such as searches, sorts and selections are developed from first

principles, and that you do not use the built-in features of a programming language for any of these routines.

11. All data structures must be defined and declared by you, the programmer. You may not use

components provided within the interface to store and later retrieve data.

SECTION B OBJECT ORIENTED PROGRAMMING The theatre at the National Theatre School of South Africa holds 180 people and the organisation keeps track of the bookings for each show separately. The theatre layout has 12 rows of chairs with 15 chairs in each row. Rows are labelled from A (at the front) to L (at the back). The theatre allows theatre-goers to book for shows via an online website called TechnoTickets. The bookings are written to a text file called bookings.txt. This file needs to be processed to determine booked seats and outstanding seats. For any given show bookings can either be individual bookings or group bookings. Individual bookings are single bookings with a seat reference, contact number and payment status recorded. Each booking is made separately and is not connected to any other booking. Group bookings are when 4 or more consecutive seats are booked. In addition to seat reference, contact number and payment status, a group name and group size is recorded for each group booking. For example, a group booking of 10 seats will be 10 separate bookings linked by the group name and size. After some consideration you decide on the following class structure:

You have been given a file called bookings.txt which contains a list of bookings for a single show at the theatre. The first 25 lines of the file are provided below for your reference (the actual file contains many more lines and you are advised to study it closely).

Booking

GroupBooking



Each line has either three or five fields present and are separated by commas. The first three fields of any line indicate the seat reference that has been booked, the contact phone number for that booking and a 'Yes' or 'No' indicating whether the booking has been paid for in full. Lines in the file that only have three fields indicate an individual booking. Lines which have two extra fields (five fields in total) represent group bookings. The additional fields represent the name of the group and the size of the group respectively. If a group of 6 people have placed a booking this will be represented as 6 separate lines in the text file. Each line of the group booking will be identical except for the seat reference which will differ. In the example data above Kolby Girls High School have booked 12 seats. The seats are B1 to B12. Each line indicates a different seat reference while the other fields are the same. These 12 entries belong to a single group due to the Group Name (the 4th field) being the same (Kolby Girls High School) for each line. The group size of 12 indicates that there are twelve seats booked for this group. The cost of any booking is based on the seat that is being booked. In addition group bookings get a further discount. The full price of a ticket is R200 but seats in rows further from the front have discounts associated with them. In addition, groups who book get R20 discount for every four members of the group. This means a group of eight will get a further R40 discount on each of their tickets while a group of 15 will get a discount of R60 on each of their tickets. The row discount is applied before the group discount in the case of group bookings. QUESTION 2 Use the class diagram below to create a new class called Booking. This class will be used to create objects that will store the details of an individual booking. The diagram below indicates the properties and methods that are required. Booking Properties: - String seat - String contact - boolean paid Methods: + Constructor(String st, String ct, boolean pd) + getCost() : double + getSeat() : String + isPaid() : boolean + toString() : String

2.1 Write code to create a new class called Booking. (1) 2.2 Write code to create the three properties for the Booking class as indicated in the

above class diagram. (3) 2.3 Write code to create a constructor method that will initialise all three properties of

the Booking class. (2)



2.4 Write code to create a method called getCost. This method should return the cost of the seat based on the row of the seat. The full price of a ticket is R200 and discounts are applied as follows:

Rows A – D : Full Price Rows E – H : 20% discount Rows I – L : 40% discount For example, if the person is seated in row K they should receive 40% discount on

their R200 ticket, making the cost of that ticket R200 – R80 = R120. (5) 2.5 Write code to create accessor methods for the paid and seat properties. (2) 2.6 Write code to create a toString method which will return a String comprised of the

seat reference and the cost (rounded to two decimal places). In addition, if the booking has been paid for the letters 'Pd' should be added onto the end of the returned string. The String must be formatted as follows:

seat reference <tab> R cost <tab> payment status for example: A1 R200.00 Pd (4) [17] QUESTION 3 Use the class diagram below to create a new class called GroupBooking. This class is a subclass of the Booking class and will be used to create objects that will store the details of a group booking. The diagram below indicates the properties and methods that are required. GroupBooking Properties: - String groupName - Integer groupSize Methods: + Constructor(String st, String ct, boolean pd, String gn, Integer gs) + getCost() : double + getGroupName() : String + toString() : String

3.1 Write code to create a new class called GroupBooking which extends the Booking

class. (2) 3.2 Write code to create two properties that will store the group name and group size

associated with a group booking. Choose appropriate data types for these properties. These values should not be visible from outside the class. (3)

3.3 Write code to create a constructor method that will initialise both of these additional

properties as well as the properties of the parent class. (3)



3.4 Write code to override the parent class's getCost method. The result of this method should be the cost of a standard booking (as per the parent method) with the group discount applied afterwards, for example the Melville Boy Scouts have booked 13 seats in row G as a group booking. Seats in row G means they qualify for a 20% discount bringing the cost of each ticket to R160. They receive a further R60 discount on each ticket due to their group size having 3 complete sets of four, bringing the final cost of each of their tickets to R100. (A group receives R20 discount for each set of four people.) (4)

3.5 Write a code to create an accessor method called getGroupName which returns the name of the group as a string. (1)

3.6 Write code to override the parent class's toString method. In addition to the details

returned from the inherited method you should add the group name to the end of the returned String in the following format:

seat reference <tab> R cost <tab> payment status for example: B1 R140.00 Pd Kolby Girls High School (3) [16]

QUESTION 4 4.1 Write code to create a new class called BookingManager. (1) 4.2 Write code to declare two instance variables in the class of a ONE-

DIMENSIONAL array that can be used to store up to 180 Booking or GroupBooking objects. Also declare an integer counter to keep track of how many Bookings are stored in the array. These two instance variables should not be accessible from outside the class. (4)

4.3 Write code to create a constructor method that will read the contents of the file

bookings.txt. Each line in the file contains information on a single Booking or GroupBooking object. Read each line from the file and instantiate the appropriate type of object (Booking or GroupBooking) and add it into the array. Note in the case of GroupBookings you must create an object in the array for each member of the group. This means for a group booking of six you will have six separate GroupBooking objects in the array. (8)

4.4 Write code that will create a method called listAllBookings. This method should

return a string that contains the information of all bookings for the show. Each booking should appear on its own line. Use the object's toString methods that you created in the questions above. (5)



4.5 Write code to create a method called listGroupBookings. This method should return a String with the name of each group on a new line. Each group name should be listed only once. In other words, if there are six GroupBooking objects, you need to list the group name of that group only once. The correct output is as follows: (7)

Group Bookings -------------- Kolby Girls High School

Knysna Retirement Home

Witbank Hockey Club

Mellville Boy Scouts

Cape Town Drama Society

Durban Gentleman's Club

4.6 Write code to create a method called outstandingPayments to calculate the total

amount owing. This method should return a real number that represents the amount of money that is still outstanding. Only objects whose paid attribute is false will have their ticket cost added to this total. The correct output is as follows: (5)

Outstanding Payments -------------------- Outstanding Payments : R 8760.0

[30]

QUESTION 5 5.1 Write code to create a simple user interface called TheatreManager which will

declare and instantiate a BookingManager object at the appropriate place in the code. (2)

5.2 Write code that will display the following by calling the appropriate methods in the

BookingManager class. You must call the methods in the following order:

All Bookings Group Bookings Outstanding Payments (3)

[5]



QUESTION 6 6.1 The theatre is interested in displaying a list of empty seats based on the bookings

they have received and are stored in the array. The following diagram shows the layout of the theatre.

An empty seat is one that is not listed as a seat in the list of bookings. In other words, if the seat reference A4 is not present in any of the bookings it is considered to be an empty seat.

Write code to create the appropriate methods in any of the classes which will help you to achieve this. Your method should return a single string representing the empty seats in the theatre. The correct output is provided below. (11)

Empty Seats ----------- A4 B13 B14 B15 C1 C9 C12 C13 C15 D1 E2 E4 E15 F13 G1 G2 H4 H15 I2 I8 I14 I15 J15

6.2 Add a call statement in the TheatreManager interface which will display a list of

empty seats. (1) [12]

INFORMATION TECHNOLOGY: PRACTICAL EXAMINATION

INSTRUCTIONS TO TEACHERS 1. For the examination requirements for Information Technology please read pages 3 – 5 of

the Subject Assessment Guidelines.

2. The school will receive a data disk containing files for the examination. These should be checked by the Information Technology teacher two days before the examination. Please refer to the instructions concerning data files supplied on page 3. Copies of the data are provided later in this document for your reference.

3. Do not open the sealed envelopes containing the examination papers and marking

guidelines until the day of the examination.

4. Each candidate must be supplied with a disk (or space on a network drive) for his/her exclusive use throughout the examination. (a) No candidate may have access to another candidate's work during the examination. (b) Disable any shared folders on the network.

(c) Ensure that the candidates cannot use their own flash drives or memory sticks. If

your candidates normally use usernames and passwords then create a new username for each candidate.

5. Please ensure that the machines have been checked and all extraneous data/programs have

been removed. Disable communications programs that will allow chatting or messaging. Ensure that no communication can take place between machines.

6. No candidate may access the Internet during the examination. 7. Information Technology teachers are allowed to invigilate the Information Technology

examinations in case there are problems with the hardware and system software. Obviously, they may not assist the candidates in any way with their particular program(s).

8. The candidates may use the help facility that has been supplied with the programming

language's software. They may not use any other manuals or documentation. In the case of Java, they may use the standard APIs available on the java.sun.com site. These should be downloaded before the examination and copied onto each candidate's disk space provided for the examination.

NATIONAL SENIOR CERTIFICATE: INFORMATION TECHNOLOGY: PRACTICAL EXAMINATION Page 2 of 15 INSTRUCTIONS TO TEACHERS


9. The three hours of the examination does not include printing time. It is exclusively for coding. At the end of the three hours, printing must be done either by the candidates, or if conditions are not suitable for this, by the Information Technology teacher. No code or data may be altered after the three-hour time period has expired.

10. Teachers must inform their candidates what printing arrangements have been made at their

school.

11. In case of a power failure or other technical interruption, all candidates must remain silent and under examination conditions. Once the interruption has passed, candidates will have only the time that was remaining when the interruption began. No candidate may receive extra time to compensate for work lost from not saving prior to the interruption.

12. Please note that the Information Technology question paper has been divided into two

sections: the first is for Structured Query Language (SQL) and the second for Object Oriented Programming. The two sections may be answered in any order and are independent of each other.

13. INSTRUCTIONS FOR MARKING AND SUBMITTING THIS PRACTICAL EXAMINATION APPEAR ON THE MARKING GU IDELINES. PLEASE PAY CLOSE ATTENTION TO THIS DOCUMENT WHEN IT IS RELEASED.



TO THE TEACHER RESPONSIBLE FOR CANDIDATES IN THE INFORMATION TECHNOLOGY PRACTICAL EXAMINATION INSTRUCTIONS CONCERNING DATA FILES SUPPLIED ON DISK You have been supplied with files on a CD. It is the responsibility of the Information Technology teacher to check two days before the examination that they can open the files and that the files can be read by the relevant applications. Printouts of the files are given, starting on the page following this document. The details of the files are as follows: Files for Learners: Please consult the folders on the CD. These are the important files only. Section A: SQL Answer Sheet.rtf TheatreDB.mdb TheatreDB.sql (MySQL import) SQL Browser software Section B: bookings.txt If you have any problems with accessing the files on disk, please notify the IEB immediately. Individual copies of these files will be required by each candidate writing the Information Technology Practical Examination. Please copy the relevant files onto a disk for each candidate's exclusive use, or onto the disk space that will be used exclusively by each candidate. The candidates are asked, in the question paper, to create backups of these files. However, it may be wise to keep a fresh set of these files on a flash drive so that copies may be quickly distributed to candidates who might alter their files and not have a backup to restore from. Teachers are advised to supply only those files that are needed for the pupils in their centre (don't supply the MySQL files if your candidates are writing with Access or vice versa). Confidentiality is of the utmost importance. Under no circumstances should candidates have access to these files before the examination. After the examination, create a folder for each candidate using their name and examination number. Copy ALL the candidate's files into their particular folder. Be sure to include the data files that are accessed by the program. Ensure that the candidates have not used path names for the data files in their programs. If candidates have used full path names, the files sent to the IEB must reflect this. Teachers may change the code for the purpose of validating the program, but may NOT overwrite the original file. The CD should contain an exact copy of the candidates' work as it existed when the examination finished. Send the CD with the marked practical examinations to the IEB. Ensure that you have attended the cluster group meetings and have used the updated mark schemes to mark all the practical exams.

SCENARIO Herkonstruksie van die mens ... Kundiges van 'n biometriese ingenieurspan voorspel dat bioniese tegnologie ons in die toekoms langer, gesonder lewens sal gee. 'Herkonstruksie van die mens' ondersoek 'n paar merkwaardige deurbrake in die ontwerp van prostetiese ledemate, kunsmatige organe, bene en selfs bloedselle. Bioniese ledemate met masjienintelligensie kan nou hul omgewing waarneem en 'n gebruiker se bedoelings voorspel. Slimmer, sterker, vinniger robotika sal een van die dae die krag van gesonde mense versterk. 'n Nuwe prostetiese arm wat in werklikheid saamgestel is uit 'n swetterjoel robotte, elkeen met 'n los segment wat 'n verwerker huisves wat saam met die ander werk, bring nuwe hoop vir baie mense.

VRAAG 4 4.1 Onderskei tussen stelselsagteware en toepassingsagteware. (2) 4.2 Dit is belangrik dat die biometriese ingenieurspan 'n li sensie-ooreenkoms het

wanneer sagteware gekoop word.

4.2.1 Beteken dit dat die span nou die sagteware besit? (1) 4.2.2 Motiveer jou antwoord op Vraag 4.2.1. (1)

4.3 Regverdig hoe elkeen van die volgende voordelig is vir die span se netwerk:

4.3.1 Brandmuur (2) 4.3.2 Teenvirussagteware (2)

4.3.3 RAID (2)

4.4 Biometriese toestelle word by die deur van die span se rekenaarlaboratorium geïnstalleer vir bywoningsbeheerdoeleindes en sekuriteit. Die bestuurder van die biometriese ingenieurspan het byvoorbeeld 'n vingerafdrukleser om die laboratorium oop te sluit. 4.4.1 Noem TWEE ander voorbeelde van biometriese toestelle en stelsels, buiten

'n vingerafdrukleser, wat vir hierdie doeleindes gebruik kan word. (2) 4.4.2 Dink jy dit is 'n skending van privaatheid om mense se vingerafdrukke te

skandeer voor hulle toegang tot 'n plek verkry? Gee TWEE redes vir jou antwoord. (3)

4.5 Rekenaarsagteware skakel intydse spieraktiwiteitseine in robotiese armbewegings

om, veral vir die gebruik van prostesebeheer. Geheuetoekenning is 'n intydse taak wat rekenhulpbronne deel en is dus meer kritiek in 'n Intydse Bedryfstelsel as in ander Bedryfstelsels.

4.5.1 Wat beteken 'Intyds'? (2)

4.5.2 Virtuele geheue is een van die metodes wat ontwikkel is om die doeltreffendheid van geheuebestuur te verhoog. Verduidelik hoe dit moontlik is. (4)

4.6 SYS/BIOS is nog 'n voorbeeld van 'n Intydse Bedryfstelsel. SYS/BIOS verskaf 'n

groot reeks stelseldienste vir 'n ingebedde toepassing soos antisiperende multitaakverwerking.

4.6.1 Definieer multitaakverwerking en multiryging. (4) 4.6.2 As verwerkers deesdae almal 'n dubbelkern het, dink jy dat multiryging

steeds nodig is in 'n toepassing? Gee TWEE redes vir jou antwoord. (3) 4.7 Hoe sal 'onderbrekings' met 'prop in en speel' saamwerk sodat 'n toestel wat

ingeprop word direk daarna vir die gebruiker beskikbaar kan wees? (2) [30]



VRAAG 5 5.1 Twitter kan 'n transformasie in die samelewing teweeg bring. Stem óf saam met óf

verskil van hierdie stelling deur TWEE argumente te verskaf. Regverdig elke argument. (4)

5.2 Die biometriese ingenieurspan is ook betrokke by natuurbewaring. Met die huidige

benarde posisie van renosters het die personeel besluit om 'n renosterwag te begin aangesien hulle 'n klompie renosters in die bewaringsgebied het. Werknemers van die maatskappy gaan naweke op wildstaptogte en twiet die posisie van die renosters en enige ander interessante waarnemings.

5.2.1 Stel 'n hutsetiket vir die twiets voor. (1)

5.2.2 Dink jy dit is 'n goeie idee om die posisies van die renosters te twiet? Regverdig jou antwoord. (2)

5.3 Die bewaringsgroep het ook raad nodig om 'n interaktiewe Internetwerf te bedryf

om bewaringskwessies met die groter gemeenskap te bespreek. Hulle is nie seker wat om te kies nie: 'n blog, wiki of forum.

Verduidelik hierdie terme en hul verskille kortliks. 5.3.1 Blog (2) 5.3.2 Wiki (2) 5.3.3 Forum (2) 5.4 Kies in die volgende scenario die toepaslikste (Blog, Wiki, Forum): Scenario: Ontwikkel gesamentlik 'n bewaringsbeleid. Verduidelik die rede vir jou keuse. (2) [15]



VRAAG 6

Die biometriese ingenieurspan moet aspekte hanteer van die verkryging van kwotasies vir toerusting om hul IT-infrastruktuur op te stel. Die eerste taak is om 'n databasis te skep om die kwotasies (kosteberamings) te stoor wat vir die verskaffing van toerusting ingedien sal word. Een van die taakspanlede het die databasis wat hieronder getoon word, opgestel. Vi r elke item is 'n minimum van drie kwotasies nodig. Party maatskappye sal meer as een kwotasie (kosteberaming) verskaf.

Verwantskappe: • Een tot een: Elke maatskappy het sy eie unieke kode en sy eie naam, adres en e-pos. • Een tot baie: Elke maatskappy kan meer as een kwotasie per dag verskaf. • Baie tot baie: Kwotasies kan baie items bevat en items kan op baie verskillende kwotasies verskyn.

6.1 Verduidelik die doel van 'n primêre sleutel in 'n databasistabel. (2) 6.2 Daar is verskeie probleme met die ontwerp van hierdie databasis. Die stappe

hieronder is deel van die proses om die ontwerpprobleme op te los.

6.2.1 Al die datatipes is as teks verklaar. Dui TWEE velde aan wat nie 'n tekstipe moet wees nie en dui die toepaslike datatipe aan vir ELKEEN van die velde wat jy geïdentifiseer het. (4)

6.2.2 In die lig daarvan dat baie maatskappye veelvuldige kwotasies (koste-beramings) het, wat is die duidelikste swakheid van die ontwerp van die Kwotasiestabel wat betref die vaslegging van data op 'n kwotasie? Jy MOET jou redenasie verduidelik. (2)

6.2.3 'n Swak ontwerpte databasis kan tot foute lei terwyl normale, alledaagse databasisinstandhoudingstake uitgevoer word. Hierdie foute word dikwels 'ongerymdhede' genoem. Noem DRIE van die ongerymdhede wat kan ontstaan as gevolg van 'n swak ontwerpte databasis. (3)

6.2.4 Die gegewe tabel bevat in werklikheid inligting oor minstens TWEE afsonderlike groepe of kategorieë data. Normaliseer die databasis tot 3NF (Derde Normaalvorm). Skryf die antwoord as 'n stel relasies. Jy MOET die volgende toon:

• Die velde wat elkeen van die nuwe tabelle sal bevat. (3) • Die primêre sleutel van elke tabel. (3) • Die vreemde sleutels en die tabelle wat die vreemde sleutels sal bevat, moet verhoudings/skakels tussen die tabelle vestig. (3)



6.3 Deel van 'n goeie databasisontwerp is om foute wanneer data ingesleutel word, vooruit te loop en te voorkom. Beskou die data wat oor die kwotasie vasgelê kan word. Die taakspan het besluit dat hulle nie kwotasies sal aanvaar vir minder as 100 eenhede of meer as 5 000 eenhede nie.

6.3.1 Wat is die tegniek wat gebruik kan word om te verseker dat data binne 'n

bepaalde bestek val? (1) 6.3.2 Skryf die reël uit wat jy sal gebruik om te verseker dat die getal eenhede

wat ingesleutel word nie buite die bepaalde bestek sal wees nie. Gebruik die veldname uit Figuur 6.1. (2)

VRAAG 7 Die biometriese ingenieurspan wil 'n eenvoudige rekenaarvasvraspeletjie skryf om feite oor renosters te onderrig. In die speletjie 'Om die renoster te red' moet tien vrae binne dertig sekondes korrek beantwoord word. Vir 'n korrekte antwoord kry jy nog 'n renoster, andersins verloor jy 'n renoster. Die vrae sal daarop gemik wees om korrekte feite oor renosters (bv. renosterhoring is NIE 'n effektiewe afrodisiak of 'n kuur vir kanker nie) aan te teken en ander feite oor renosters te onderrig. Daar is TWEE tipes vrae: WAAR of ONWAAR en MEERVOUDIGE KEUSE met DRIE opsies. Die vrae en korrekte antwoorde word in 'n tekslêer gestoor. Hieronder is die klasdiagramme vir elke tipe vraag:

VraagOb VraagWO VraagMeerKeuse

− vraag:String − vraag:String

− TF:Boole

− vraag:String

− antwoord:String

− a, b, c:String

7.1 Die klasse hierbo kan vereenvoudig word deur oorerwing te gebruik. Teken die

klasdiagramme, toon oorerwing duidelik aan en verwyder enige onnodige velde of metodes. (3)

7.2 Gee TWEE voordele van oorerwing. (2)

7.3 Wat beteken polimorfie? (2)

7.4 Parameters is fundamenteel tot programmering. Beskryf hoe die volgende konsepte

met mekaar verband hou:

7.4.1 Formele parameters (2) 7.4.2 Argumente (2)

7.5 Probleem: Toevoer en geldigheidstoetsing van 'n (20)-syfergetal. • Die getal sal geldig wees as en slegs as die twintigste (20ste) syfer gelyk is aan

die res van die som van die eerste negentien (19) syfers gedeel deur 20. • Die program moet 'n geskikte boodskap druk wat die gebruiker inlig of die getal geldig of ongeldig is.

7.5.1 Verklaar enige veranderlike(s) wat nodig is om die 20-syfergetal hierbo te

stoor. (2) 7.5.2 Gebruik vervolgens die veranderlikes (datastruktuur) wat in Vraag 7.5.1

verklaar is en skryf die algoritme wat die toevoer en geldigheidstoetsing van 'n (20)-syfergetal moontlik sal maak. (7)

NASIONALE SENIORSERTIFIKAAT-EKSAMEN NOVEMBER 2013

INLIGTINGSTEGNOLOGIE : VRAESTEL II Tyd: 3 uur 120 punte LEES ASSEBLIEF DIE VOLGENDE INSTRUKSIES NOUKEURIG DEUR 1. Hierdie vraestel bestaan uit 12 bladsye. Maak asseblief seker dat jou vraestel volledig is. 2. Hierdie vraestel moet beantwoord word deur objekgeoriënteerde programmeringsbeginsels

te gebruik. Jou program moet sinvol gebruik maak van metodes en parameters. 3. Hierdie vraestel is in twee afdelings verdeel. Alle kandidate moet albei afdelings

beantwoord. 4. Hierdie vraestel is opgestel in programmeerterme wat nie kenmerkend is vir enige

spesifieke programmeertaal (Java/Delphi) of databasis (Access/MySQL) nie. 5. Maak seker dat jy die vrae beantwoord op die wyse wat beskryf word, aangesien punte vir

jou oplossing toegeken sal word ooreenkomstig die spesifikasies wat in die vraag gegee word.

6. Beantwoord slegs wat in elke vraag gevra word. As die vraag byvoorbeeld nie vra vir

datageldigheidstoetsing nie, word geen punte daarvoor toegeken nie en hoef geen kode dus geskryf te word nie.

7. As jy 'n gedeelte van die kode nie kan laat werk nie, moet jy dit as kommentaar merk sodat

dit nie uitgevoer word nie en sodat jy met die eksamen kan voortgaan. Probeer indien moontlik om die fout te verduidelik om die nasiener te help.

8. Wanneer jy in jou kode toegang tot 'n lêer verkry, MOENIE die name van die volledige pad

van die lêer gebruik nie, aangesien dit probleme sal skep wanneer die program nagesien word op 'n ander rekenaar as die een waarop jy werk. Verwys bloot na die lêers deur die name en uitbreidings daarvan te gebruik waar nodig.

9. Jou programme moet op so 'n manier gekodeer word dat hulle met enige data sal werk en

nie slegs die voorbeelddata wat voorsien is of enige data-uittreksels wat in die vraestel voorkom nie. Jy word aangeraai om die datalêers wat voorsien word, noukeurig te bestudeer.

10. Maak seker dat roetines soos soektogte, sorterings en selekterings uit eerste beginsels

ontwikkel word en dat jy nie die ingeboude eienskappe van 'n programmeertaal vir enigeen van hierdie roetines gebruik nie.

NASIONALE SENIORSERTIFIKAAT: INLIGTINGSTEGNOLOGIE: VRAESTEL II Bladsy 2 van 12


11. Alle datastrukture moet deur jou, die programmeerder, gedefinieer en verklaar word. Jy mag nie komponente wat binne die koppelvlak voorsien word, gebruik om data te stoor en later te herwin nie.

12. Lees die hele vraestel voordat jy 'n datastruktuur kies. Dit mag wees dat daar 'n

alternatiewe metode is om die data voor te stel wat dalk meer doeltreffend sal wees met inagneming van die vrae wat in die vraestel gevra word.

13. Jy moet al jou werk gereeld stoor op die skyf wat jy ontvang het of die skyfspasie wat vir

hierdie eksamen aan jou toegeken is. 14. As daar 'n tegniese onderbreking is wat verhoed dat jy jou eksamen kan skryf (byvoorbeeld

'n kragonderbreking), sal jy wanneer jy weer begin skryf slegs die tyd gegee word wat oor was toe die onderbreking begin het. Geen ekstra tyd sal gegee word om werk wat nie gestoor is nie weer oor te doen nie.

15. Maak seker jou eksamennommer verskyn as kommentaar in elke program wat jy kodeer,

sowel as op elke bladsy sigkopie wat jy inlewer. 16. Druk 'n kodelys van al die programme/klasse wat jy kodeer. Drukwerk moet na die

eksamen gedoen word. Jy sal na afloop van die eksamen 'n halfuur ontvang om te druk. Jou onderwyser sal jou inlig oor die reëlings vir die druk van jou werk.

SCENARIO Die Nasionale Teaterskool van Suid-Afrika bied in November 'n William Shakespeare Fees aan en wil verskeie rekenaarstelsels gebruik wanneer hierdie geleentheid gereël word. Jy word gevra om hulle te help met databasis- en programmeringsverwante werk.



AFDELING A GESTRUKTUREERDE NAVRAAGTAAL Jy word gevra om vir doeleindes van die fees nuttige inligting oor opvoerings en akteurs uit die databasis te onttrek. Daar is drie tabelle in die databasis om inligting oor die opvoerings (almal Shakespeare-dramas) en die akteurs wat in hierdie produksies optree, te stoor. Die akteurs se persoonlike besonderhede word gestoor in 'n tabel genaamd tblAkteurs , die inligting oor die verskillende opvoerings (byvoorbeeld datum, tyd, kapasiteit en koste) word gestoor in 'n tabel genaamd tblOpvoerings en 'n lys van watter akteurs die rolle in elke drama speel, word gestoor in 'n tabel genaamd tblRolle. Die velde in die databasis word hieronder bespreek. Onder elke beskrywing is 'n skermkiekie van die eerste 10 rye data vir jou gerief. Die tabelle bevat meer data: tblAkteurs AkteurID Dit is 'n veld met outomatiese nommering wat aan elke akteur 'n

unieke ID-nommer toeken AkteurNaam Hierdie veld bevat die name van die akteurs AkteurGDatum Hierdie veld bevat die geboortedatums van die akteurs AkteurTarief Hierdie veld bevat die bedrag geld in rand wat die akteur elke uur of

AFDELING B OBJEKGEORIËNTEERDE PROGRAMMERING Die teater by die Nasionale Teaterskool van Suid-Afrika het sitplek vir 180 mense en die organisasie bly op die hoogte van die besprekings vir elke opvoering afsonderlik. Die teateruitleg het 12 rye stoele met 15 stoele in elke ry. Rye is gemerk van A (voor) tot L (agter). Die teater laat teatergangers toe om via 'n gekoppelde webwerf genaamd TechnoKaartjies vir opvoerings te bespreek. Die besprekings word na 'n tekslêer genaamd besprekings.txt geskryf. Hierdie lêer moet verwerk word om bespreekte sitplekke en beskikbare sitplekke te bepaal. Vir enige gegewe opvoering kan besprekings óf individu ele besprekings óf groepbesprekings wees. Individu ele besprekings is enkelbesprekings met 'n sitplekverwysing, kontaknommer en betalingstatus aangeteken. Elke bespreking word afsonderlik gedoen en is nie met enige ander bespreking verbind nie. Vir Groepbesprekings word 4 of meer opeenvolgende sitplekke bespreek. Benewens sitplekverwysing, kontaknommer en betalingstatus word 'n groepnaam en groepgrootte vir elke groepbespreking aangeteken. 'n Groepbespreking van 10 sitplekke sal byvoorbeeld 10 afsonderlike besprekings verbind deur die groepnaam en -grootte wees. Na oorweging besluit jy op die volgende klasstruktuur:

Jy het 'n lêer genaamd besprekings.txt ontvang wat 'n lys van besprekings vir 'n enkele opvoering by die teater bevat. Die eerste 25 reëls van die lêer word hieronder verskaf vir jou verwysing (die werklike lêer bevat baie meer reëls en jy word aangeraai om dit noukeurig te bestudeer).

GroepBespreking

Bespreking



Elke reël het óf drie óf vyf velde aanwesig wat deur kommas geskei word. Die eerste drie velde van enige reël dui die sitplekverwysing aan wat bespreek is, die kontaktelefoon-nommer vir die bespreking en 'n 'Ja' of 'Nee' wat aandui of die bespreking ten volle betaal is of nie. Reëls in die lêer wat slegs drie velde het, dui 'n individu ele bespreking aan. Reëls wat twee ekstra velde het (vyf velde in totaal), verteenwoordig groepbesprekings. Die bykomende velde verteenwoordig onderskeidelik die naam van die groep en die grootte van die groep. Indien 'n groep van 6 mense 'n bespreking gedoen het, sal dit as 6 afsonderlike reëls in die tekslêer voorgestel word. Elke reël van die groepbespreking sal identies wees, behalwe vir die sitplekverwysings wat sal verskil. In die voorbeelddata hierbo het Kolby Girls High School 12 sitplekke bespreek. Die sitplekke is B1 tot B12. Elke reël dui 'n ander sitplekverwysing aan, terwyl die res van die velde dieselfde is. Hierdie 12 inskrywings behoort aan 'n enkele groep omdat die groep-naam (die 4de veld) dieselfde is (Kolby Girls High School) vir elke reël. Die groepgrootte van 12 dui aan dat daar twaalf sitplekke vir hierdie groep bespreek is. Die koste van enige bespreking word gebaseer op die sitplek wat bespreek word. Boonop kry groepbesprekings 'n verdere afslag. Die volle prys van 'n kaartjie is R200, maar sitplekke in rye verder van voor af word met afslag geassosieer. Verder kry groepe wat bespreek, R20 afslag vir elke vier lede van die groep. Dit beteken dat 'n groep van agt 'n verdere R40 afslag op hul kaartjies kry, terwyl 'n groep van 15 'n afslag van R60 op elkeen van hul kaartjies sal kry. Die ry-afslag word voor die groepafslag toegepas in die geval van groepbesprekings. VRAAG 2 Gebruik die klasdiagram hieronder om 'n nuwe klas genaamd Bespreking te skep. Hierdie klas sal gebruik word om objekte te skep wat die besonderhede van 'n individuele bespreking sal stoor. Die diagram hieronder dui die eienskappe en metodes aan wat benodig word. Bespreking Eienskappe: - String sitplek - String kontak - boolean betaal Metodes: + Constructor(String sp, String kt, boolean bt) + kryKoste() : double + krySitplek() : String + isBetaal () : boolean + naString() : String

2.1 Skryf kode om 'n nuwe klas genaamd Bespreking te skep. (1) 2.2 Skryf kode om die drie eienskappe vir die Bespreking-klas te skep soos in die

klasdiagram hierbo aangedui. (3) 2.3 Skryf kode om 'n konstruktormetode te skep wat al drie eienskappe van die

Bespreking-klas sal inisialiseer. (2)



2.4 Skryf kode om 'n metode genaamd kryK oste te skep. Hierdie metode moet die koste van die sitplek op grond van die ry van die sitplek terugstuur. Die volle prys van 'n kaartjie is R200 en afslag word soos volg toegepas:

Ry A – D : Volle prys Ry E – H : 20% afslag Ry I – L : 40% afslag As mense byvoorbeeld in ry K sit, moet hulle 40% afslag op hul R200-kaartjie

ontvang, wat die koste van die kaartjie R200 – R80 = R120 maak. (5) 2.5 Skryf kode om toegangermetodes vir die betaal- en sitplekeienskap te skep. (2) 2.6 Skryf kode om 'n naString-metode te skep wat 'n string bestaande uit die sitplek-

verwysing en die koste (afgerond tot twee desimale plekke) sal terugstuur. As die bespreking boonop betaal is, moet die letters 'Bt' aan die einde van die terug-gestuurde string bygevoeg word. Die string moet soos volg geformateer word:

sitplekverwysing <tab> R koste <tab> betalingstatus byvoorbeeld: A1 R200.00 Bt (4) [17] VRAAG 3 Gebruik die klasdiagram hieronder om 'n nuwe klas genaamd GroepBespreking te skep. Hierdie klas is 'n subklas van die Bespreking-klas en sal gebruik word om objekte te skep wat die besonderhede van 'n groepbespreking sal stoor. Die diagram hieronder dui die eienskappe en metodes aan wat benodig word. GroepBespreking Eienskappe: - String groepNaam - Integer groepGrootte Metodes: + Constructor(String sp, String kt, boolean bt, String gn, Integer gg) + kryKoste() : double + kryGroepNaam() : String + naString() : String

3.1 Skryf kode om 'n nuwe klas genaamd GroepBespreking te skep wat die

Bespreking-klas uitbrei. (2) 3.2 Skryf kode om twee eienskappe te skep wat die groepnaam en groepgrootte sal

stoor wat met 'n groepbespreking geassosieer word. Kies toepaslike datatipes vir hierdie eienskappe. Hierdie waardes moenie van buite die klas sigbaar wees nie. (3)

3.3 Skryf kode om 'n konstruktormetode te skep wat beide hierdie bykomende

eienskappe sowel as die eienskappe van die ouerklas sal inisialiseer. (3)



3.4 Skryf kode om die ouerklas se kry Koste-metode te oorskryf. Die resultaat van hierdie metode moet die koste van 'n standaardbespreking (volgens die ouermetode) wees met die groepafslag daarna toegepas, byvoorbeeld die Melville Boy Scouts wat 13 sitplekke in ry G as groepbespreking bespreek het. Sitplekke in ry G beteken hulle kwalifiseer vir 'n 20%-afslag wat die koste van elke kaartjie op R160 te staan bring. Hulle ontvang 'n verdere R60 afslag op elke kaartjie omdat hul groepgrootte 3 volledige stelle van vier het, wat die finale koste van elkeen van hul kaartjies op R100 te staan bring. ('n Groep ontvang R20 afslag vir elke stel van vier mense.) (4)

3.5 Skryf kode om 'n toegangermetode genaamd kryGroepNaam te skep wat die naam van die groep as 'n string terugstuur. (1)

3.6 Skryf kode om die ouerklas se naString metode te oorskryf. Benewens die

besonderhede wat van die oorgeërfde metode teruggestuur word, moet jy die groepnaam aan die einde van die teruggestuurde string byvoeg in die volgende formaat:

sitplekverwysing <tab> R koste <tab> betalingstatus byvoorbeeld: B1 R140.00 Bt Kolby Girls High School (3) [16]

VRAAG 4 4.1 Skryf kode om 'n nuwe klas genaamd BesprekingBestuurder te skep. (1) 4.2 Skryf kode om twee instansieveranderlikes in die klas van 'n EENDIMENSIONELE

skikking te verklaar wat gebruik kan word om tot 180 Bespreking- of GroepBespreking-objekte te stoor. Verklaar ook 'n heelgetalteller om op die spoor te bly van hoeveel Besprekings in die skikking gestoor word. Hierdie twee instansieveranderlikes moenie van buite die klas toeganklik wees nie. (4)

4.3 Skryf kode om 'n konstruktormetode te skep wat die inhoud van die lêer

besprekings.txt sal lees. Elke reël in die lêer bevat inligting oor 'n enkele Bespreking- of GroepBespreking-objek. Lees elke reël uit die lêer en instansieer die toepaslike tipe objek (Bespreking of GroepBespreking). Voeg dit in die skikking by. Let daarop dat in die geval van GroepBespreking jy 'n objek in die skikking moet skep vir elke lid van die groep. Dit beteken vir 'n groepbespreking van ses sal jy ses afsonderlike GroepBespreking-objekte in die skikking hê. (8)

4.4 Skryf kode wat 'n metode genaamd lysAlleBesprekings sal skep. Hierdie metode

moet 'n string terugstuur wat die inligting van alle besprekings vir die opvoering bevat. Elke bespreking moet in sy eie reël verskyn. Gebruik die objek se naString-metodes wat jy in die vraag hierbo geskep het. (5)



4.5 Skryf kode om 'n metode genaamd lysGroepBesprekings te skep. Hierdie metode moet 'n string terugstuur met die naam van elke groep in 'n nuwe reël. Elke groep-naam moet slegs een keer gelys word. Met ander woorde, as daar ses GroepBespreking-objekte is, moet jy die groepnaam van die groep slegs een keer lys. Die korrekte afvoer is soos volg: (7)

Groepbespreking s -------------- Kolby Girls High School

Knysna Retirement Home

Witbank Hockey Club

Mellville Boy Scouts

Cape Town Drama Society

Durban Gentleman's Club

4.6 Skryf kode om 'n metode genaamd uitstaandeBetalings te skep om die totale

bedrag verskuldig te bereken. Hierdie metode moet 'n reële getal terugstuur wat die bedrag geld wat nog uitstaande is, verteenwoordig. Slegs objekte waarvan die betaal-kenmerk onwaar is se kaartjiekoste sal by hierdie totaal bygevoeg word. Die korrekte afvoer is soos volg: (5)

Uitsta ande Betalings -------------------- Uitsta ande Betalings : R 8760.0

'n Oop sitplek is een wat nie as 'n sitplek in die lys besprekings genoem word nie. Met ander woorde, as die sitplekverwysing A4 nie in enigeen van die besprekings aanwesig is nie, word dit as 'n oop sitplek beskou.

Skryf kode om die toepaslike metodes te skep in enigeen van die klasse wat jou sal help om dit reg te kry. Jou metode moet 'n enkele string terugstuur wat die oop sitplekke in die teater verteenwoordig. Die korrekte afvoer word hieronder verskaf. (11)
