2.2 System Design The system objective outlined during the system analysis serve as the basis from which
the work of system design is initiated. Much of the activities involved at this stage is of
technical nature requiring a certain amount of degree of experience in designing
systems, sound knowledge of computer related technology and thorough understanding
of computers related technology. Nevertheless a system cannot be designed in isolation
without the active involvement of the user. The user has a vital role to play at this stage
too. As we know that data collected during the system requirement analysis will be
utilized systematically at this stage. Depending on the plan of system analysis, the level
of detailed study will vary and the system design stage will also vary in the amount of
investigations that still need to be done. This investigation is generally an activity
during the system design as the designer need to study the minute details in all aspects
of the system . Designing a new system is a creative process which calls for logical as
well as lateral thinking. The logical approach involves systematic moves towards the
end product keeping in mind the capabilities of the personnel and the equipment at each
decision making step. Lateral thought implies encompassing of ideas beyond the usual
functions and equipments.
16
2.2.1 SYSTEM DESIGN CONSTRAINTS
The system design process is not a step by step adherence of clear procedures and
guidelines. When designer starts working on system design he will face different types
of problems. Many of these will be due to the constraints imposed by the use or
limitations of the hardware and software available in the market.
2.2.2 THE PRIMARY OBJECTIVE OF THE DESIGN IS:
Of course to deliver the requirements as specified in the SRS. In general, the following
design objectives should be kept in mind:
Practicality : The system must be stable and can be operated by people with
average IQ.
Efficiency: This involves accuracy, timeliness and comprehensiveness of the
system output.
Cost: It is desirable to aim for a system with a minimum cost subject to the
condition that it must satisfy all the requirements.
Flexibility : The system should be modifiable depending on the changing
needs of the user.
Security: This is very important aspect of the design and should cover areas of
hardware reliability, fall back procedures, physical security of data and
provision for detection of fraud and abuse.
17
2.2.3 MAJOR SYSTEM DESIGN ACTIVITIES
Several development activities are carried out during structured design. They are data
base design, implementation planning, system test preparation, system interface
specification and user documentation.
Database Design : This activity deals with the design of the physical database.
A key is to determine how the access paths are to be implemented.
Program Design : In conjunction with database design is a decision on the
programming language to be used and the flowcharting, coding and the
debugging procedure prior to conversion. The operating system limits the
programming languages that will run of the system.
System and Program Test Preparation : Each aspect of the system has a
separate test requirement. System testing is done after all programming and
testing is completed. The test cases cover every aspect of the proposed system,
actual operations user interface and so on.
18
2.2.4 Use case Diagram:
A use case diagram is a diagram which consists of set of usecases and actors enclosed by system boundary, and association between usecases and actors. Usecases diagram especially important in organizing, modeling the behavior of the system.
Use case is a set of scenarious tied together by a common user goal. A scenario is a sequence of steps describing the interaction between a user and system.

Chapter III: Flowcharts & Data Flow Diagrams
3.1 System Flow Charts
22
A flow chart is defined as a pictorial representation describing a process being studied or even used to plan stages of a project. Flow charts tend to provide people with a common language or reference point when dealing with a project or process.Four particular types of flow charts have proven useful when dealing with a process analysis: top-down flow chart, detailed flow chart, work flow diagrams, and a deployment chart. Each of the different types of flow charts tends to provide a different aspect to a process or a task. Flow charts provide an excellent form ofdocumentation for a process, and quite often are useful when examining how various steps in a process work together.When dealing with a process flow chart, two separate stages of the process should be considered: the finished product and the making of the product. In order to analyze the finished product or how to operate the process, flow charts tend to use simple and easily recognizable symbols. The basic flow chart symbols below are used when analyzing how to operate a process.

3.2 Data Flow Diagrams
25
A graphical tool used to describe and analyze the moment of data through a system manual or automated including the process, stores of data, and delays in the system. Data Flow Diagrams are the central tool and the basis from which other components are developed. The transformation of data from input to output, through processes, may be described logically and independently of the physical components associated with the system. The DFD is also known as a data flow graph or a bubble chart. A graphical tool used to describe and analyze the moment of data through a system manual or automated including the process, stores of data, and delays in the system.

Context Diagram
The top-level diagram is often called a “context diagram”. It contains a single process, but it plays a very important role in studying the current system. The context diagram defines the system that will be studied in the sense that it determines the boundaries. Anything that is not inside the process identified in the context diagram will not be part of the system study.

Chapter IV: Testing
31
4.1 System Testing In this stages the test group of the development team, using the cases and the test data already prepared will test the programs. Only after all the functions are tested singularly, an integrated testing will be performed to see that inter-function dependability is satisfied. Separate test cases and test data will be worked out for the integrated testing.
Any system, to be successful, must be thoroughly tested, and well managed test plan should be prepared before actual testing is being performed. “Modules” have been developed and need to be tested in a manner that can reduce occurring of defects as low as possible. Following are the activities we planned to test the system.
1. This system is indeed an evolutionary system so every unit of the system is continuously under testing phase.
2. One test activity “Basis Path Testing” that will try to cover all paths in the system. This activity identifies all paths that provide different functionality of the system, and also other paths to reach at that functionality.
3. Other testing activity is”Control Structure Testing”, which will test each and every condition with positive and negative data combination.
4. This testing activity will also perform “Data Flow Testing” in which it will be tested how the data re following the system. And will also check whether the data entered from one procedure, is reflected whenever it requires or not.
5. All conditions will be tested with “Boundary Value Analysis” where different input will be given to test whether the system is functioning with boundary values or not.
6. Along with the boundary value analysis, the system is also tested with “Range Value Tested” where editable values will be tested with ranges of values.
7. The system is being tested in “Unit Testing” manner where at the completion of one unit that is tested thoroughly with above mentioned testing activities.
8. The integration testing will also be performed to ensure that the integrated unit is working properly with other units or not.
32
4.2 Test Levels
4.2.1 CONTENT TESTING:
Errors in Project content can be as trivial as minor typographical error as incorrect information, improper organization or validation of intellectual property laws. Content Testing attempt to uncover this and many other problems before the user encounter them.
Content Testing Objectives:There are three types of objectives.
To uncover syntactic errors in text-based documents, graphical representation and other media.
To uncover semantic errors in any content object represented as navigation error.
To find errors in organization or structure of content that is presented to the end-user
4.2.2 INTERFACE TESTING:
Interface design model is reviewed to ensure that generic quality criteria established for all user interfaces have been achieved and that application specific interface design issue has been properly addressed.
Interface testing strategy:The overall strategy for interface testing is to (1) Uncover error related to specific Interface mechanisms (2) uncover errors in the way the interface implements the semantics of navigation, Web Application functionality, or content display. To accomplish this strategy, a number of objectives must be achieved:
Interface futures are tested to ensure that design rules, aesthetics and related visual content are available for the user without error.
Individual interface mechanisms are tested in a manner that is analogous to unit testing For example; tests are designed to exercise all forms, client-side scripting, dynamic XML.
33
Testing Interface Mechanisms:- When a user interacts with a system, the interaction occurs through one or more interface mechanisms. Forms: - At a microscopic level, tests are performed to ensure that
Labels correctly identified fields within the form and that mandatory fields are identified visually for the user.
The server receives all information content within the form and their no data are lost in the transmission between client and server.
Appropriate defaults are used when the user does not select from a pull down menu or set of buttons.
Browsing functions don’t corrupt data entered in the form.
Scripts that perform error checking on data entered work.
Properly and provide meaningful error message.
Client side scripting:- Black box tests are conducted to uncover any error in processing asThe script is executed. These tests are coupled with forms testing because script input is often derived from data provided as part of forms processing
Dynamic XML:-
Here the data transfer between the systems occurs in the form of XML file. The formatting of the XML file should remain unaltered. Changes in the internal attribute structure can also lead to an error. Hence for this XML parsing functionalities are provided on the client side.
Application specific interface mechanisms:-Test conforms to a checklist of functionality and features that are defined by the interface mechanism.
Boundary test minimum and maximum number of item that can be placed in to shopping chart.
Test to determine persistence of image capture contents.
34
Test to determine whether the system can be record co-ordinate content at some future date.
4.2.3 USABLITY TESTING:-
Usability test may be designed by Project engineering team.
Define a set of usability testing categories and identify goal for each.
Design test that will enable each goal to be evaluated.
Select participants who will conduct test.
Instrument participant’s interaction with system while testing is conducted.
Develop a mechanism for assessing the usability of the system.
The following test categories and objective illustrate establish testing:-
Interactivity- Are interaction mechanism easy to understand and use?
Layout- Are navigation mechanism, content and function place in a manner that allows the user to find them quickly?
Readability- Is the text well written and clear?
Aesthetics- Do layout color, typeface, and related characteristics lead to ease of use?
Display Characteristics- Does the system make optimal use of screen size and resolution?
Time Sensitivity- Can important features, functions and content be used in a timely manner? Accessibility- Is the system accessible to people who have Disabilities?
4.2.4 COMPATIBILITY TESTING:-Project must operate within environment that differs from one another. Different computer, display device, OS, browser and network connection speed can have significant on system operation. The Project team derives a series of compatibility,
35
validation tests, derived from existing interface tests, navigation tests, performance tests and security tests.
4.3 Testing MethodsAnalyze and check system representation such as the requirement document, design diagrams and the program source code. They may be applied at all stages of the process.
There are different Models of testing. On the basis of testing methods there are two types of testing:
1. White-box testing.
2. Black-box testing
Unit Testing
Module Testing
Sub-system Testing
System Testing
Acceptance Testing
36
1. WHITE-BOX TESTINGWhite-box testing sometimes called glass-box testing, is a test case design method that users the control structure of the procedural design to drive the test case.
Logical errors and incorrect assumption are inversely proportional to the probability that a program will be executed. Errors tend to creep into our work we design and implement function, condition or control that is out of the mainstream tends to be well understood.
We often believe that a logical path is not likely to be executed when in fact it may be executed on a regular basis. The logical flow of a program times counter intuitive.
2. BLACK-BOX TESTING:For our project periodically we have tested our software using black-box testing. Thinking as a client we have evaluated the software for its easy going and convenience.
Unit Testing:
During the programming stages each and every form, modules and class treated unit has been put into the test data. Every module is tested independently. The steps are follows:
Manually code is tested like spelling checks, logic and errors. Once the manual checking is over the complication has been done. Syntactical
errors if any have to be corrected. After the clean complication the program, some dummy data, as specification,
has been used for testing of the module to see if it works as specified.
Integration Testing:
After our individual’s modules were tested out we go the integrated to create a complete system. This integration process involves building the system and testing the resultant system for problems that arise from component interaction.
Performance Testing:
Performance testing is designed to test the runtime performance of the system within the context of the system. These tests were performed as module level as well as system level. Individual modules were tested for required performance.
Condition Testing:
37
Performance testing is a test case design method that exercises the logical conditions.
Interface Testing:
Interface sting is integral part of integration. We examined the code to be tested and explicitly list each call to an external component. In the system standards tests for GUIs have been performed, which are as follows:
The position and related labels for all controls were checked. Validations for all inputs were done. Pull down controls was verified for proper functionality. Whether the non-editable text controls disabling and it was also verified that it
doesn’t exceed the maximum allowed length.
4.4 Test Cases

6.1 Conclusion
This Real Estate Web Application is a typical .NET web application using
ASP.NET 2.0and ms access 2005 in the vb programming language.
It uses a client/server architecture based on the HTTP protocol. It is developed
in Microsoft’s Visual Studio .NET programming environment.
The buyer performs a search for the property listings by putting either Zip
code/City/State in the search textbox. The business logic tier communicates
with the database tier requesting the results of the query sent by it.
The results obtained by the database are displayed on the data grid, by
refreshing the grid rather than refreshing the entire web page. Efficiency of the
application is improved by the use of web methods that help in separating
Application Tier from the Presentation Tier.
The performance of this application is evaluated by rigorously testing it against
various test scenarios. Some ways in which this system could be enhanced with
additional functionalities are discussed in the section.
58
6.2 Future Scope of the system
This project is developed as a master’s project and still gives lot of scope for its
extension which could be made to the project if it is going to be developed as
commercial product.
We can use pure object-oriented domain model to deal the database access tier
using Visual Studio 2005and ms access 2005. In doing this, we can get a better
architecture design which will improve code efficiency and running
performance.
Besides, we can build XML web service programming model that enables other
applications to consume real estate web services built by us using standard
protocol such as HTTP, XML, and web services description language(WSDL).
This project just deals with the Home page and Search page to search for
property listings, more functionality can be added for searching the agents and
offices making it a complete application.
The feature of providing Google Maps within this application adds up to the
functionality of the website. With the advancement of technology, dynamic
maps can be generated which can help the buyer locate a particular area where
the property is located in the Google Map.
Inclusion of all these features would make the application feature rich. The
advantages of putting these functionalities in the project are described in detail
in the following sections.

APPENDIX-I
A I.1 SOFTWARE SPECIFICATION
SOFTWARE REQUIREMENTS SPECIFICATION
A Software Requirements Specification (SRS) is a complete description of the behavior
of the system to be developed. It includes a set of use cases that describe all the
interactions the users will have with the software. Use cases are also known as
functional requirements. In addition to use cases, the SRS also contains nonfunctional
(or supplementary) requirements. Non-functional requirements are requirements
which impose constraints on the design or implementation (such as performance
engineering requirements, quality standards, or design constraints).
DESIGN SPECIFICATION
Design specifications are the measurements and characteristics of a structure or object
which provide for a workable, sustainable, or pleasing creation or construct. This can
apply to a wide variety of manufactured or fabricated objects, such as buildings,
automobiles, and clothes and also utility, computing, and distribution systems. Any
functional thing made by human beings has certain specific details.
FUNCTIONAL SPECIFICATION
In software development, a functional specification (also, functional spec or specs or
functional specifications document (FSD) or Program specification) is the set of
documentation that describes the requested behavior of an engineering system. The
documentation typically describes what is needed by the system user (design-goal),
which internal functions are necessary, as well as, requested properties of inputs and
outputs (for ex. of the software system). As a design document, a functional
specification does not typically define the inner workings of the proposed system, it
61
means it does not yet include the specification how the system function will be
implemented. Instead, it focuses on what various outside agents (people using the
program, computer peripherals, or other computers, for example) might "observe"
when interacting with the system
PRODUCT DESIGN SPECIFICATION
A product design specification (PDS) is a statement of what a not-yet-designed product
is intended to do. Its aim is to ensure that the subsequent design and development of a
product meets the needs of the user.[1]
The PDS acts as an initial boundary in the development of products. However, it will
naturally evolve as it is progressed through the different stages of the design process.[2]
REQUIREMENTS ANALYSIS
In systems engineering and software engineering, requirements analysis encompasses
those tasks that go into determining the needs or conditions to meet for a new or altered
product, taking account of the possibly conflicting requirements of the various
stakeholders, such as beneficiaries or users. Systematic requirements analysis is also
known as requirements engineering[1]. It is sometimes referred to loosely by names
such as requirements gathering, requirements capture, or requirements specification.
The term requirements analysis can also be applied specifically to the analysis proper
(as opposed to elicitation or documentation of the requirements, for instance
SOFTWARE DEVELOPMENT PROCESS
A software development process is a structure imposed on the development of a
software product. Synonyms include software life cycle and software process. There
62
are several models for such processes, each describing approaches to a variety of tasks
or activities that take place during the process.
SPECIFICATION (TECHNICAL STANDARD)
A specification is an explicit set of requirements to be satisfied by a material,
product, or service.
USE OF A SPECIFICATION
In engineering, manufacturing, and business, it is vital for suppliers, purchasers, and
users of materials, products, or services to understand and agree upon all requirements.
A specification is a type of a standard which is often referenced by a contract or
procurement document. It provides the necessary details about the specific
requirements.
Specifications may be written by government agencies, standards organizations
(ASTM, ISO, CEN, etc), trade associations, corporations, and others.
A product specification does not necessarily prove the product to be correct. Just
because an item is stamped with a specification number does not, by itself, indicate that
the item is fit for any particular use. The people who use the item (engineers, trade
unions, etc) or specify the item (building codes, government, industry, etc) have the
responsibility to consider the available specifications, specify the correct one, enforce
compliance, and use the item correctly. Validation of suitability is necessary.
63
SPECIFICATION AND DESCRIPTION LANGUAGE
Specification and Description Language (SDL) is a specification language targeted at
the unambiguous specification and description of the behaviour of reactive and
distributed systems. It is defined by the ITU-T (Recommendation Z.100.) Originally
focused on telecommunication systems, its current areas of application include process
control and real-time applications in general.
SDL provides both a graphical Graphic Representation (SDL/GR) as well as a textual
Phrase Representation (SDL/PR), which are both equivalent representations of the
same underlying semantics. A system is specified as a set of interconnected abstract
machines which are extensions of finite state machines (FSM).
SYSTEM REQUIREMENTS
To be used efficiently, all computer software needs certain hardware components or
other software resources to be present on a computer system. These pre-requisites are
known as (computer) system requirements and are often used as a guideline as opposed
to an absolute rule. Most software defines two sets of system requirements: minimum
and recommended. With increasing demand for higher processing power and resources
in newer versions of software, system requirements tend to increase over time. Industry
analysts suggest that this trend plays a bigger part in driving upgrades to existing
computer systems than technological advancements

A I.2 PHYSICAL SPECIFICATIONS
DATA FLOW DIAGRAM
It is common practice for a designer to draw a context-level DFD first which shows the
interaction between the system and outside entities. The DFD is designed to show how
a system is divided into smaller portions and to highlight the flow of data between
those parts. This context-level DFD is then "exploded" to show more detail of the
system being modeled.
Data flow diagrams were invented by Larry Constantine, the original developer of
structured design, based on Martin and Estrin's "data flow graph" model of
computation.
Data flow diagrams (DFDs) are one of the three essential perspectives of Structured
Systems Analysis and Design Method SSADM. The sponsor of a project and the end
users will need to be briefed and consulted throughout all stages of a system's
evolution. With a dataflow diagram, users are able to visualize how the system will
operate, what the system will accomplish, and how the system will be implemented.
The old system's dataflow diagrams can be drawn up and compared with the new
system's dataflow diagrams to draw comparisons to implement a more efficient system.
Dataflow diagrams can be used to provide the end user with a physical idea of where
the data they input ultimately has an effect upon the structure of the whole system from
order to dispatch to restock. How any system is developed can be determined through a
dataflow diagram.
Developing a DFD helps in identifying the transaction data in the data model.
65
There are different notations to draw data flow diagrams, defining different visual
representations for processes, datastores, dataflow, and external entities.

66
DFD LEVELS
A context level DFD created using Select SSADM.
A Level 0 DFD for the same system.
A Level 1 DFD showing the "Process Enquiry" process for the same system.
CONTEXT LEVEL
This level shows the overall context of the system and it's operating
environment and shows the whole system as just one process. It does not
usually show data stores, unless they are "owned" by external systems, e.g.
are accessed by but not maintained by this system, however, these are often
shown as external entities.
LEVEL 0
This level shows all processes at the first level of numbering, data stores,
external entities and the data flows between them. The purpose of this
level is to show the major high level processes of the system and their
interrelation. A process model will have one, and only one, level 0
diagram. A level 0 diagram must be balanced with it's parent context level
diagram, i.e. there must be the same external entities and the same data
flows, these can be broken down to more detail in the level 0, e.g. the
"enquiry" data flow could be spilt into "enquiry request" and "enquiry
results" and still be valid
LEVEL 1
This level is a decomposition of a process shown in a level 0 diagram, as
such there should be a level 1 diagram for each and every process shown
in a level 0 diagram. In this example processes 1.1, 1.2 & 1.3 are all
children of process 1, together they wholly and completely describe
process 1, and combined must perform the full capacity of this parent
67
process. As before, a level 1 diagram must be balanced with it's parent
level 0 diagram
ENTITY- RELATIONSHIP MODEL
An entity-relationship model (ERM) is an abstract conceptual representation of
structured data. Entity-relationship modeling is a relational schema database modeling
method, used in software engineering to produce a type of conceptual data model (or
semantic data model) of a system, often a relational database, and its requirements in a
top-down fashion. Diagrams created using this process are called entity-relationship
diagrams, or ER diagrams or ERDs for short.
Originally proposed in 1976 by Peter Chen, many variants of the process have
subsequently been devised.
The first stage of information system design uses these models during the requirements
analysis to describe information needs or the type of information that is to be stored in
a database. The data modeling technique can be used to describe any ontology (i.e. an
overview and classifications of used terms and their relationships) for a certain universe
of discourse (i.e. area of interest). In the case of the design of an information system
that is based on a database, the conceptual data model is, at a later stage (usually called
logical design), mapped to a logical data model, such as the relational model; this in
turn is mapped to a physical model during physical design. Note that sometimes, both
of these phases are referred to as "physical design".
An entity may be defined as a thing which is recognised as being capable of an
independent existence and which can be uniquely identified. An entity is an abstraction
from the complexities of some domain. When we speak of an entity we normally speak
of some aspect of the real world which can be distinguished from other aspects of the
real world .
68
An entity may be a physical object such as a house or a car, an event such as a house
sale or a car service, or a concept such as a customer transaction or order. Although the
term entity is the one most commonly used, following Chen we should really
distinguish between an entity and an entity-type. An entity-type is a category. An
entity, strictly speaking, is an instance of a given entity-type. There are usually many
instances of an entity-type. Because the term entity-type is somewhat cumbersome,
most people tend to use the term entity as a synonym for this term.
Entities can be thought of as nouns. Examples: a computer, an employee, a song, a
mathematical theorem. Entities are represented as rectangles.
A relationship captures how two or more entities are related to one another.
Relationships can be thought of as verbs, linking two or more nouns.
Entities and relationships can both have attributes. Examples: an employee entity might
have a Social Security Number (SSN) attribute; the proved relationship may have a date
attribute. Attributes are represented as ellipses connected to their owning entity sets by
a line.
Every entity (unless it is a weak entity) must have a minimal set of uniquely identifying
attributes, which is called the entity's primary key.
Entity-relationship diagrams don't show single entities or single instances of relations.
Rather, they show entity sets and relationship sets. Example: a particular song is an
entity. The collection of all songs in a database is an entity set. The eaten relationship
between a child and her lunch is a single relationship. The set of all such child-lunch
relationships in a database is a relationship set.
Lines are drawn between entity sets and the relationship sets they are involved in. If all
entities in an entity set must participate in the relationship set, a thick or double line is
drawn. This is called a participation constraint. If each entity of the entity set can
participate in at most one relationship in the relationship set, an arrow is drawn from
the entity set to the relationship set. This is called a key constraint. To indicate that
each entity in the entity set is involved in exactly one relationship, a thick arrow is
drawn.
