PROBLEM DEFINITION

HARDWARE AND SOFTWARE CONFIGURATION

The Hardware and Software Configuration for the proposed system is given below.

Hardware Configuration:-

For the successful run of the proposed system the required stand alone Personal Computer with, minimum hardware required to run the system is as below.

Hardware Minimum Requirement

Processor Pentium 2Hard disk 4 GBRAM 64 MBDot Matrix Printer 16 Pin

Software Configuration:-

The minimum Software required by the system is follows.

1. ORACLE as Back End.2. Visual Basic 6.0 as Front End

The reason for selecting ORACLE and Visual Basic as tools are as follows.

Features of ORACLE : -

It is a high performance, full tolerant relational database management System especially designed for large database application.

It offers following benefits: It eliminates all parent-child relationships and instead

represented all data in the database as simple row/column tables of data values.

Flexibility in data modeling. Easy for accessing data. Each table is an independent entity and there is no physical

relationship between tables. Reduce data storage and redundancy.


PROBLEM DEFINITION

Independent of physical storage and logical data design.

It has wide level data manipulation language (SQL). Most data management system based on the relational model

has a built-in support for query languages like ANSI SQL or QBE (Query By Example). These queries are simple English constructs that allow adhoc data manipulation from a table.

Deferred writing at commits to improve transaction performance. Security and control. It has a rollback command for recreating the database to its

most recent safe point. Grant and revoke limits access to information down to row and column level. Views are valuable features for limiting access to the primary tackles in the database.

Professional ORACLE starts the DBMS (Database Management System) in the extended memory, so more main memory is available for other applications.

Relational model of data management is based on set theory. Built-in query language is designed in the RDBMS, so that it can manipulate sets of data (one or more tuples).

User interface used with relational models is non-procedural because only what needs to be done is specified and not how it has to be done. Using any of the other methods, you have not only to specify what need to be done but how it has to be done as well.


PROBLEM DEFINITION

Features of Visual Basic 6.0 : -

Visual Basic provides complete set of tools to simplify rapid application Development.

It provides a vital link to graphical environment and allows you to develop applications based on standard windows features: Dialog boxes, Command buttons, Pull down menus, Scroll Bars, Selection lists etc. It also allows creating robust applications that fully make use of the graphical user interface.

ActiveX Data Objects (ADO) and OLE DB replace the Open database connectivity (ODBC) API as the preferred method for accessing shared file and client/server databases.

Internet techniques such as Dynamic HTML (DHML), Extensible markup language (XML), Active server pages (ASP) and ActiveX documents offer browser-based alternatives for displaying and updating data.

Extensions to Visual Basic class modules assist in writing middle-tier DLLs for Microsoft transaction server 2.0.

A multitude of wizards and other graphical tools aid developers new to Visual Basic.

Visual Basic is an event driven programming language. Visual Basic allows you to adopt more of parallel approach, with

independent sections of code for each option that the user may select. This is known as Event driven programming language.

Data Environment Designer (DED). Drag and drop form generation. Data view window. ADO Data Control (ADODC). ADO-compliant data-bound controls. Hierarchical record sets and the Flex Grid Control. Data report design. Data form wizards. Format objects. Data repeater control. Data source classes and data building. MTS transaction Mode property of Class modules. Visual data tools (VDTS). SQL editor. Component creation. Language. Packaging and Deployment wizard. Data object wizard. The integrated development environment.


PROBLEM DEFINITION

INTRODUCTION TO EXISTING SYSTEM

The Company follows a manual system for maintaining the Airline Reservation System.

Whenever any requisition comes to the Counter to issue a ticket the firstly the Ticket Capacity checked whether the required quantity of the ticket is present or not. If the required tickets is present then issue a ticket and update the reservation information and an entry is done to the Ticket Issue Register.The day-to-day entries are made manually into the book that has gotten all the relevant entries.

Check the Ticket Quantity regularly whether any ticket is not in, if so then Ticket Issue process is cancelled. In the same way Ticket cancellation is followed. If Fare is increased or decreased then changes into Fare Book. If New Flight is introduced then entry on relevant book, that process applies to Flight-Schedule, Airbus, and Branch.At the end of the year or when an intermediate report is needed then prepare the report is required.LIMITATIONS OF THE EXISTING SYSTEMThe Existing system includes problems like lack of time consuming, accuracy, high cost, security problems, etc.There are many problems in existing systems like:Time and speed

Man power High cost Security Complexity Maintenance Accuracy Storing Records might get lost or be insufficient due to manual errors. Maintaining and managing data is very costly and time

consuming, because there are many documents that have to be maintained by each branch and copies have to be transferred to relative branches.

Transfer of information within the branches is costly and time consuming.


PROBLEM DEFINITION

INTRODUCTION TO PROPOSED SYSTEM

There are many activities that can be computerized in this widely spread organization. The current context is related to maintain the ticket Reservation-Cancel ticket. The important reason is to make-work easy. No need to search a Flight register for entry or any other transaction.

Computerization of this must fulfilled the requirements of working staff due to effective work of computer in terms of efficiency, speed, accuracy, storage capacity and quickness.

Even though it is costly, it is recommended the computerization of the ticket issue process.


PROBLEM DEFINITION

OBJECTIVES OF PROPOSED SYSTEM

Manual work has to be reduced. Get accuracy. Result to be received very quickly. It uses concept of user friendliness. It provides using of multiple applications at a time. Increase security, speed, storing and accuracy. Customer services can not only be satisfied but also enhanced to the

extent that one can obtain or cancel a reservation from any branch for any route at any given time.

To speed up the operation. Managing and maintaining data becomes easier. Provide convenience to travelers. It decreases manpower and high cost.


PROBLEM DEFINITION

FEATURES OF PROPOSED SYSTEM

Manual work has to be reduced and Result to be received quickly.To speed up the operation and Decrease manpower, high cost.Increase security, speed, storing and accuracy.The customers have to face only one person at the booking counter for obtain the reservation.

Managing and maintaining data becomes easier and cost effective due to very high amount and reliability of storage space available in the proposed system. It provides support for queries through out all the branches at any given time at a very high speed, saving a lot of time.

The system has been developed under Microsoft Visual Basic 6.0 as a Front-End tool and Oracle 8.0 as a Back-End tool.


PROBLEM DEFINITION

ADVANTAGES OF PROPOSED SYSTEM

The proposed system due to computerized is much faster in reservation process, cancellation process and transactions.

Transfer of information from various branches would become easier and faster.

Managing and maintaining data becomes easier and cost effective due to very high amount and reliability of storage space available in the proposed system.

Customer services can not only be satisfied but also enhanced to the extent that one can obtain or cancel a reservation from any given time.


PROBLEM DEFINITION

LIMITATIONS FOR PROPOSED SYSTEM

The main limitation of system is if any plane that not stop in a particular destination that have not been included in airline reservation system.

Per ticket only one other services are included at a time.

Passenger cannot transfer his/her reservation from one flight to another flight.


PROBLEM DEFINITION

FEASIBILITY STUDY & COST BENEFIT ANALYSIS

Feasibility study is most important and it concerns great to the passenger, for which new system is to be developed. It includes the study of success and level of satisfaction that the passenger and the user will get from the system. Feasibility means possibilities (to some extent), i.e. this study explores the possibility of implementation of new system as a substitute to old system removing all shortcomings and including all new requirements.

An initial determine in a proposal that whether an alternative system is feasible or not. To determine feasibility of candidate system in all respect I need to consider following feasibility factors:

Economical feasibility Technical feasibility Behavioral feasibility

ECONOMICAL FEASIBILITY::-

Since the existing system is manual, the organization posses the computer and doesn’t require to set the environment.

Cost involved in the software packages includes the ORACLE 8.0 for storage of data as a back end. Other required software is that which they already have like WINDOWS 98. This costs around Rs.45, 000/- for the oracle software.

As the new system size is round 3.5 KDL the cost involved in developing the system is retrieved as follows:Size of project = 3.5 KDL.


PROBLEM DEFINITION

Organic Project.

Here, a=3.2 and b=1.05

The cost drivers and their rating for our project are as follows:

Cost Drivers Category Rating Reliability High 1.15Database Size Very high 1.16Complexity Low 0.70Analyst Capacity Normal 1.00Analyst Experience Very low 1.29Programmer Capacity Normal 1.00Language Experience Normal 1.00

The cost of the project is estimated by the below formula as follows:

Ei = a * (size)b

= 3.2 * (3.5) 1.05

= 11.923

EAF = 1.15*1.16*0.70*1.00*1.29*1.00*1.00 = 1.20

E = Ei * EAF = 11.923 * 1.20 = 14.30 PM

If we assume the average salary for the person is about Rs.7, 000/- per month then the cost is:

Cost = 14.30 * 7000 =100100

So the total cost including the cost of the oracle the RDBMS is: Total Cost = 1,00,100+45,000

= 1,45,100

Hence the total cost of my project is Rs.1, 45,100/-Also the total duration for the entire project is:Here the value of a=2.5 and b=0.38

D = a * (E) b

= 2.5 * (14.30)0.38

= 6.870


PROBLEM DEFINITION

So the estimated duration for the project is 7 months approximately.

TECHNICAL FEASIBILITY::-

It is determined by the hardware and supporting software.Hardware requirement: stand-alone computer with enough main memory space & backup storage more than 2 GB to support RDBMS and huge database.

Software requirement: ORACLE.

BEHAVIOURAL FEASIBILITY: -

It includes training the user staff on the candidate system. The data entry design is similar to other forms being used by the user staff. Data entry forms are very user friendly and data entry job has been kept minimum. So training of 3-4 will be sufficient. Even for generating reports the user has to supply 2-3 parameters only.


PROBLEM DEFINITION

REQUIREMENT ANALYSIS

As we have decided to develop a new system now it is time to determine the new requirements for the new system. As the user is the most important part of any system it is required to find the users requirements to develop a user-friendly system rather than having to develop a developer friendly system.

The outputs required by the user that must be included into the proposed system are as follows:

1. The work for the particular user must be personalized.

2. Passport and valid visa are required for ticket booking.

3. Tickets are print as in required order.

4. The user must be provided easy if he wants to switch from one application to other at a time.


PROBLEM DEFINITION

FACT GATHERING TECHNIQUES

PROBLEM DEFINITION

DATA FLOW DIAGRAM

As information moves through software, it is modified by a series of transformations. A Data Flow Diagram (DFD) is a graphical technique that depicts information flow and the transformations that are applied as data move from input to output. The data flow diagram is know as a data flow graph or a bubble chart.

The Data Flow Diagram may be used to representation a system or software at any level of abstraction. In fact, DFDs may be used partitioned into levels that represent increasing information flow and functional detail. Therefore, the DFD provides a mechanism for functional modeling as information flow modeling.

The Data Flow Diagram (DFD) serves two purposes:

1) To provide an indication of how data are transformed as they move through the system and2) To depict the functions that transform the data flow. The DFD provides additional information that is used during the analysis of the information domain and serves as a basis for the modeling of function.

A Level 0 DFD also called as fundamental system model or a context model, represents the entire software element as a single bubble with input and output data indicated by incoming and outgoing arrows respectively. Additional processes and information flow paths are represented as the level 0 is partitioned to reveal details. Each of the proves represents at level 1 is sub function of the overall system depicted in the context model. Each of the process may be refined are layered to depict more detail. Information continuity must be maintained in every layer, that is input and output to each refinement must remain the same.

PROBLEM DEFINITION

DATA DICTIONARY

Data Dictionary is a store of information about the data in database. The dictionary defines the name, description, source of data, users of data, and keywords in data, formula to derive the data, specification and such other details. Data dictionary brings common understanding of the data in the organization. RDBMS provides software to create the dictionary. Use of data dictionary enforces the standards of processing, usage’s application and documentation in the organization.

Data Dictionaries are an integral component of structured analysis, since data flow diagram by them do not fully describe the information about the system. The data dictionary provides additional information about the system.

A data dictionary is a catalogue – a repository – of the elements in a system. These elements center on data the way they are structured to meet user requirements and organization needs. In a data dictionary, a list of all the elements composing the data flowing through a system is included. If a project team member wants to know the definition of a data item name or the contents of a particular data flow, the information will be available in the data dictionary. Descriptions of all data used in the system are given in a data dictionary.


PROBLEM DEFINITION

Analysts use Data Dictionary for five important reasons.

1) To manage the detail in large systems.

2) To communicate a common meaning for all system elements.

3) To document the features of the system.

4) To facilitate analysis of the details in order to evaluate characteristics and determine where system changes should be made.

5) To locate errors and omissions in the system.

TESTING PROCEDURE AND SYSTEM IMPLEMENTATION PHASES


PROBLEM DEFINITION

System testing is an important but critical part of system. Module testing involves the process of testing the logical units of program individually and integrating the individual modules, to test the overall system. The objective of module testing is to determine whether the module meets its specifications.

In order to perform module testing two things are to be considered: the design of test cases and the coordination of the multiple modules. Test cases may be constructed from specification or by analyzing the module code. The testing strategies corresponding to tests two approaches are called as black box and white box testing. In black box testing the internal structure and behavior of the program is not considered. In white box testing the structure of the program is examined and test data are derived from the program’s logic. In non-incremental approach testing modules independently and then combining them to the program without further testing test a program. In the incremental approach a module is tested in combinations with the set of previously tested modules.

The testing plans areas that are to be tested.

1) Testing for data entry error: -Incorrect data entry, leads to incorrect results. Sometimes

it may creates run time errors. So data should be checked for validity.

2) Testing for basic principles: -If all processing is in order but display of the screens is

disorderly then that has to be rectified and such screen can confuse the user. User will be left wondering on the next actions to be taken. In some of the cases operator/user has the habit of certain key for particular option. In such cases users requirements are taken into consideration. E.g. press Escape for Exit. In some cases. I.e. Branch code, PNR no are auto generated.

3)Testing for suitable error messages: -If the error messages are not suitable phases or incorrect

then there can be log off problems to the user who is non-professional won’t be able to figure out what exactly the error is


PROBLEM DEFINITION

E.g. if the user has entered an incorrect airbus no and if the error messages displays “invalid airbus no” then that is an error. If user pressed ESCAPE key and if nothing happens then that is also an error.

3) Testing for suitable response time: -In some cases, the results of a particular query may take

out a lot of system resources and also a longer time to process. In such cases program logic has to be rewritten. In some cases changes have been made in table.

One major factor, which has influenced the functionality of the system, is the valid data. As and when the master files were completed, the user added valid data and thus the expected results could also be verified. During testing I used incremental approach, black box testing and program instrumentation.

These processes continue till the user is fully satisfied. The data are again tested and the reports are compared with the original ones that the system should produce. The testing is done when the original data for guarantee of the outputs before it is implemented.

CONCLUSION

The Airline reservation system has been a way of minimizing the clerical work, which is almost a routine and consumes the most precious time.


PROBLEM DEFINITION

This AIRLINE RESERVATION SYSTEM has been an attempt to help the user to minimize his workload along with minimizing the paper works and saving of time.

The system has been developed in a way to make it very user friendly. It provides an on-line message and an error detection and error messages every time the user needs. Any person having a little bit of window based can run this system without any pain.

Almost all the difficulties of manual reservation have been removed by this system. Ti wind up let me welcome all the suggestions and other improvements, which the system needs so that it covers all the needs if the user in the user way.
