CHAPTER 2

SYSTEM ANALYSIS

INTRODUCTION

System analysis is a process of gathering and interpreting facts, diagnosing

problems and the information to recommend improvements on the system. It is a

problem solving activity that requires intensive communication between the system

users and system developers. System analysis or study is an important phase of any

system development process. The system analyst plays the role of the interrogator and

dwells deep into the working of the present system. The system is viewed as a whole

and the input to the system are identified. The outputs from the organizations are

traced to the various processes. System analysis is concerned with becoming aware of

the problem, identifying the relevant and decisional variables, analyzing and

synthesizing the various factors and determining an optimal or at least a satisfactory

solution or program of action.

A detailed study of the process must be made by various techniques like

interviews, questionnaires etc. The data collected by these sources must be scrutinizedto arrive to a conclusion. The conclusion is an understanding of how the system

functions. This system is called the existing system. Now the existing system is

subjected to close study and problem areas are identified. The designer now functions

as a problem solver and tries to sort out the difficulties that the enterprise faces. The

solutions are given as proposals. The proposal is then weighed with the existing

system analytically and the best one is selected. The proposal is presented to the user

for an endorsement by the user. The proposal is reviewed on user request and suitable

changes are made. This is loop that ends as soon as the user is satisfied with proposal.

2.1 EXISTING SYSTEM

In the existing system only we can see the details of particular information

aboutthe police stations in our state, the existing system has more workload for

the authorizedperson, but in the case of Proposed System, the user can registered in

our site and send thecrime report and complaint about a particular city or person.

2.1.1 Drawbacks of Existing System

More man power. Time consuming. Consumes large volume of pare work. Needs manual calculations. No direct role for the higher officials. Damage of machines due to lack of attention.

To avoid all these limitations and make the working more accurately the system needs

to be computerized.

2.2 PROPOSED SYSTEM

The aim of proposed system is to develop a system of improved facilities. The

proposed system can overcome all the limitations of the existing system. The system

provides proper security and reduces the manual work. The existing system has

several disadvantages and many more difficulties to work well. The proposed system

tries to eliminate or reduce these difficulties up to some extent. The proposed system

will help the user to reduce the workload and mental conflict. The proposed system

helps the user to work user friendly and he can easily do his jobs without time

lagging.

2.2.1 Expected Advantages of Proposed System

The system is very simple in design and to implement. The system requires

very low system resources and the system will work in almost all configurations. It

has got following features

Ensure data accuracys. Proper control of the higher officials. Reduce the damages of the machines. Minimize manual data entry. Minimum time needed for the various processing. Greater efficiency. Better service & Minimum time required User friendliness and interactive.

2.3 FEASIBILITY STUDY

Feasibility study is made to see if the project on completion will serve the

purpose of the organization for the amount of work, effort and the time that spend on

it. Feasibility study lets the developer foresee the future of the project and the

usefulness. A feasibility study of a system proposal is according to its workability,

which is the impact on the organization, ability to meet their user needs and effective

use of resources. Thus when a new application is proposed it normally goes through a

feasibility study before it is approved for development.

The document provide the feasibility of the project that is being

designed and lists various areas that were considered very carefully during the

feasibility study of this project such as Technical, Economic and Operational

feasibilities.

2.3.1 Economic Feasibility

The developing system must be justified by cost and benefit. Criteria to

ensure that effort is concentrated on project, which will give best, return at the

earliest. One of the factors, which affect the development of a new system, is the cost

it would require.

The following are some of the important financial questions asked during

preliminary investigation:

The costs conduct a full system investigation. The cost of the hardware and software. The benefits in the form of reduced costs or fewer costly errors.Since the system is developed as part of project work, there is no manual cost

to spend for the proposed system. Also all the resources are already available, it give

an indication of the system is economically possible for development.


6/63

2.3.2 Operational / Behavioral Feasibility

This includes the following questions:

Is there sufficient support for the users?

Will the proposed system cause harm?The project would be beneficial because it satisfies the objectives when

developed and installed. All behavioral aspects are considered carefully and conclude

that the project is behaviorally feasible.

2.3.3 Technical Feasibility

The system must be evaluated from the technical point of view first. The

assessment of this feasibility must be based on an outline design of the system

requirement in the terms of input, output, programs and procedures.

Having identified an outline system, the investigation must go on to suggest

the type of equipment, required method developing the system, of running the system

once it has been designed.

Technical issues raised during the investigation are:

Does the existing technology sufficient for the suggested one? Can the system expand if developed?The project should be developed such that the necessary functions and

performance are achieved within the constraints. The project is developed within

latest technology. Through the technology may become obsolete after some period of

time, due to the fact that never version of same software supports older versions, the

system may still be used. So there are minimal constraints involved with this project.

The system has been developed using ASP.NET the project is technically feasible for

development.

CHAPTER 4

SOFTWARE DESCRIPTION

OVERVIEW OF SOFTWARE

In the project Software project monitoring system .NET Framework is used as

front-end tool. .NET is one of the most beautiful and recently more popular front-end

tools. C#.NET and ASP.NET are used in this project.

An interface for users is build-using ASP.NET. SQL Server 2005 is

used as the back-end tool. Additional technologies used are Internet Information

Services (IIS) and ADO.NET. Then it comes the turn of the Operating System. Any

.NET framework compatible software platform can be used.

4.1 FRONT END

INTRODUCTION TO .NET

Microsoft .NET is a software that connects information, people,

systems and devices. It spans clients, servers and developers tools and consists of the

.NET framework used for building and running all kinds of software including Web

based application and smart client applications.

Developers tools like Microsoft Visual Studio.NET 2008 provide an

integrated development environment (IDE) for maximizing developer productivity

with the .NET framework. C# programs run on the .NET Framework, an integral

component of Windows that includes a virtual execution system called the commonlanguage runtime (CLR) and a unified set of class libraries. The CLR is Microsofts

commercial implementation of the common language infrastructure (CLI), an

international standard that is the basis for creating execution and the development

environment in which languages and libraries work together seamlessly.

Source code written in C# is compiled into an intermediate language

(IL) that conforms to the CLI specification. The IL code, along with resources such as


9/63

9

bitmaps and strings, is stored on disk in an executable file called an assembly,

typically with an extension of .exe or .dll.

When the C# program is executed, the assembly is loaded into the

CLR, which might take various actions based on the information in the manifest.

Then, if the security requirements are met, the CLR performs just in time (JIT)

compilation to convert the IL code into native machine instructions. The CLR also

provides other services related to automatic garbage collection, exception handling,

and resource management .Code that is executed by the CLR is sometimes referred to

as managed code,in contrast to unmanaged code which is compiled into native

machine language that targets a specific system. The following diagram illustrate the

compile-time and run time relationships of C# source code files, the base class

libraries, assemblies and the CLR.

ABOUT C#.NET

C#.net is a major component of Microsoft Visual Studio .NET suite. The

.NET version of C# is a new improved version with more features and additions.

Microsoft .NET is a programming and operating framework introduced by Microsoft.

All .NET supported languages access common .NET library to develop applications

and share common tools to execute applications. Programming with C# using .NET is

called C#.NET.C# is an elegant and type-safe object-oriented language that enables

developers to build a wide range of secure and robust applications that run on the

.NET Framework. We can use C# to create traditional Windows client applications,

XML Web services, distributed components, client-server applications, database

applications and much more.

Attributes, which provide declarative metadata about types at run time.

Name Spaces

As you have seen earlier, most of the .NET types are defined in

namespaces. A namespace is a scope in which managed types are defined. If you see

.NET Framework Class Library, you will see hundreds of namespaces. For example,


10/63

10

System namespaces contains types such as Console, Object and so on. If you want to

access Console class, you need to import System namespaces in your application.

A Namespace in Microsoft .Net is like containers of objects. They may

contain unions, classes, structures, interfaces, enumerators and delegates. Main goal

of using namespace in .Net is for creating a hierarchical organization of program. In

this case a developer does not need to worry about the naming conflicts of classes,

functions, variables etc., inside a project.

ASP.NET

ASP.NET is more than the next version of active server pages (ASP); it is

a unified Web development platform that provides the services necessary for

developers to build enterprises-class Web applications. While ASP.NET is largely

syntax compatible with ASP, it provides a new programming model and infrastructure

for more secure, scalable, and stable applications. You can feel free augmented your

existing ASP applications by incrementally adding ASP.NET functionally to

them.ASP.NET is a compiled, .NET based environment; you can author applications

in any .NET compatible language, including Visual Basic .NET, C# and JScirpt.NET.

Additionally, the entire .NET Framework is available to any ASP.NET

applications. Developers can easily access to benefits of these technologies, which

include the managed common language runtime environment, type safety, inheritance

and so on.

ASP.NET has been designed to work seamlessly with WYSIWYG (What

You See is What You Get) HTML editors and other programming tools, including

Microsoft Visual Studio .NET. Not only does this make a Web development easier,

but it also provide all the benefits that these tools have to offer, including a GUI that

developers can use to drop server controls on to a Web page and fully integrated

debugging support.

Internet Information Services (IIS)

ASP.NET and IIS work together to create a server program that forrequest and creates the required objects. IIS is the software that allows your computer


11/63

11

become web server and remote clients to download HTML pages (or run ASP.NET

pages). IIS is included with Microsoft windows 2000, XP and Windows .NET server.

ADO.NET

ADO.NET is a part of the .NET Framework and it is used to handle data

access. With ADO.NET you can work with databases.ADO.NET is a disconnected

database access model which means, when an application interacts with the database,

the connection is opened to serve the request of the application and is closed as soon

as the request is completed. Likewise, if a database is updated, the connection is

opened long enough to complete the Update operation and is closed. By keeping

connections open for only a minimum period of time, ADO .NET conserves system

resources and provides maximum security for databases and also has less impact on

system performance. Also, ADO .NET when interacting with the database uses

XML and converts all the data into XML format for database related operations

making them more efficient. ADO.NET consists of a set of classes used to handle data

access. ADO.NET has, unlike ADO no record set object. Its primary benefits are:

Ease of use. High speed. Low memory overhead. Small disk footprint.

ADO.NET consists of two primary parts:

i. Data providerii. Datasets

Data provider: These classes provide access to a data source, such as a Microsoft

SQL Server or Oracle database. Each data source has its own set of provider objects,

but they each have a common set of utility classes:

Datasets: Datasets objects, a group of classes describing a simple in-memory

relational database, were the star of the show in the initial release (1.0) of the

Microsoft .NET Framework.

4.2 BACK END

SQL Server 2005

A database is a collection of information thats related to a particular

subject or purpose, such as tracking client orders or maintaining a list of project

details. If the database isnt stored on a computer, or only part of it are one may be

tracking information from a variety of sources that one is having to co-ordinate and

organize himself using Microsoft SQL Server, one can manage all information from a

single database file.

Within the file, data is divided into separate storage containers calledtables; view, add and update data by using online forms; find and retrieve just the data

wanted for reports. SQL Server allows the user to view, update or analyze the

database from the Internet of an intranet by creating data access pages.

SQL Server as a relational database stores data in many related tables.

A table is a collection of data about a specific topic such as projects or clients. Using a

separate table for each topic means that, store that data only once. This makes the

database more efficient and reduces data-entry errors.

Tables organize data into columns (called fields) and rows (called

records). A common field relates two tables so that Microsoft SQL Server can bring

together the data from the two tables for viewing, editing, or printing. In table Design

view one can create an entire table from scratch or add, delete or customize the fields

in an existing table. The user can also display records from tables that are related to

the current table by displaying sub datasheets within the main datasheet.

In SQL Server a database is the overall container of data and

associated with in a single SQL Server database. To fling and retrieve just the data

that meets conditions specified, including data form multiple tables, create a query.

It is easy to use. It scales from a mobile laptop to systematic multiprocessor system. It provides data warehousing features.

4.2 FEATURES OF FRONT & BACK END TOOLS

4.2.1 Features of C#.NET

i. Inheritance: Inheritance is one of the most used techniques in an object orientedlanguage. Inheritance provides ability to use an existing classs functionality

via its derived (inherited) class. Inheritance refers to the properties of a class

being available to many other classes. The properties and methods of the base

class are inherited and extracted by the derived classes. By default all the

classes created with C#.NET are inheritable. The users can use inheritance to

define new forms designed by users are really classes.

ii. Exception Handling: Exception handling is an in build mechanism in .NET

framework to detect and run time errors. The .NET Framework contains lots of

standard exceptions. The exceptions re anomalies that occur during the

exception of program. They can be because of, logic or system errors. If a user

(programmer) does not provide a mechanism to handle these anomalies, the

.NET run time environment provides a default mechanism, which terminates

the program execution. C#.NET provides three keywords try, catch and finally

to do exception handling. Try encloses the statements that might throw anexception whereas catch handles an exception if one exist and finally can be

used for doing any clean up process.

iii. Overloading: C#.NET supports methods overloading using the overloadingKeyword. Using this keyword, you can declare same method names with

different arguments.

iv. Overriding: Overriding is the creation of a method in the subclass that the

same signature, i.e. name, number and type of arguments, as method in the

super class. This new method hides the method of super class. Derived classes

inherit the methods defined in their base class. All methods are not overridable

by default but if a method in the base class is marked with overridable keyword

the Overrides keyword can be used in derived class to define new

implementation of the inherited method.

v. Constructors and Destructors: The procedures that control initialization of

new instances of a class are known as constructors. Conversely, destructors are

methods that are used to free system resources when a class leaves scope or is


14/63

14

set to nothing.C#.NET supports constructors and destructors using the Sub

New and Sub Dispose procedures. Sub New method will only run once when a

class is created. In addition to these basic object-oriented principles, C#

facilities the development of software components through several innovative

language constructs, including:

Encapsulated method signatures called delegates, which enablestype safe event notifications.

Properties, which serves as assessors for private membervariables.

4.2.2 Features of Microsoft SQL Server 2005

Analysis Services

Fixes have been included that improve the performance and stability ofqueries.

HTTP connectivity will now support HTTP compression. Optimized queries to perspectives are now as fast as queries to the

perspectives base cube.

Data programmability

Client connection time has been significantly improved if failover occurs whilethe server is using Database Mirroring and the clients are using TCP/IP.

SQL Server 2005 Integration Services (SSIS)

Usability of the Import/Export Wizard has been improved in multiple-tablescenarios.

The IDtsPipelineEnvironmentService service lets custom data flowcomponents have programmatic access to the parent Data Flow task.

Interoperability with Analysis Services has been improved. The DataReadersource in SSIS supports the System.Object data type by converting columns

that have this data type to the DT_NTEXT ssISnoversion data type.


15/63

15

To change the data type to a type that is more appropriate for your data, youcan add a Data Conversion transformation.

Performance has been improved for many transformations, such as the Sorttransformation.

The Expression Builder dialog box now has a public and documented API.This increased access to expression-related objects will benefit task developers

because expressions are important to the way that tasks are interrelated.

In the Advanced Editor dialog box, the Flat File source has the new propertyUseBinaryFormat. This property supports loading packed decimal data into

the pipeline for processing by a script or by a custom transformation.

In the Advanced Editor dialog box, the DataReader source has the newproperty CommandTimeout. You can use this property to modify the time-

out period to allow for long-running operations.

To create or to modify the property expressions of variables, you can nowopen the Expression Builder dialog box from the Properties window.

You can now add annotations to precedence constraints.

Manageability

Profiler and Replay

Previously, Profiling Analysis Services showed the time in CoordinatedUniversal Time (UTC). The time now appears in the user's local time.

Previously, events that successfully replayed were not being counted correctly.Therefore, incorrect replay statistics were reported to the user. This problem

has been fixed.

Previously, Replay ignored the network packet size that you set when youconnected to the network. Instead, Replay always created a connection that

had a packet size of 32 kilobytes (KB). Sometimes, large playbacks would

cause the server to run out of memory. This problem has been fixed.

CHAPTER 5

PROJECT DESCRIPTION

5.1 PROBLEM DEFINITION

Problems with conventional system

1. Lack of immediate retrievals: -The information is very difficult to retrieve

and to find particular information like- E.g. - To find out about the Criminals history,

the user has to go through various registers

2. Lack of immediate information storage: - The information generated by

various transactions takes time and efforts to be stored at right place.3. Lack of prompt updating: - Various changes to information like Criminal

details or immunization details of child are difficult to make as paper work is

involved.

4. Preparation of accurate and prompt reports: - This becomes a difficult

task as information is difficult to collect from various registers.

These Problems gets rectified through this efficient crime file management

System.

5.2 OVERVIEW OF THE PROJECT

The project titled as Online Crime file Management System is a web based

application. This software provides facility for reporting online crimes, complaints,

missing persons, show most wanted person details mailing as well as chatting. Any

Number of clients can connect to the server. Each user first makes their login to sever

to show their availability. The server can be any Web Server. An SMTP Server mustbe maintained for temporary storage of emails and chat jar files for enable the chatting

facilities.

5.4 DATA FLOW DIAGRAM

Data flow oriented techniques advocate that the major data items handled by a

system must be first identified and then the processing required on these data items to

produce the desired outputs should be determined. The DFD (also called as bubble

chart) is a simple graphical formalism that can be used to represent a system in terms

of input data to the system, various processing carried out on these data, and the


19/63

output generated by the system. It was introduced by De Macro (1978), Gane and

Sarson (1979).

The primitive symbols used for constructing DFDs are:

Symbols used in DFD

- A circle represents a process.

- A rectangle represents external entity

- A square defines a source or -destinationof the system data.

- An arrow identifies dataflow.- Double line with one end closed

5.6 DATABASE DESIGN

A database is an organized mechanism that has the capability of storing

information through which a user can retrieve stored information in an effective and

efficient manner. The data is the purpose of any database and must be protected.

The database design is a two level process. In the first step, user requirements

are gathered together and a database is designed which will meet these requirements

as clearly as possible. This step is called Information Level Design and it is taken

independent of any individual DBMS.

In the second step, this Information level design is transferred into a design for

the specific DBMS that will be used to implement the system in question. This step is

called Physical Level Design, concerned with the characteristics of the specific

DBMS that will be used. A database design runs parallel with the system design. The

organization of the data in the database is aimed to achieve the following two major

objectives.

Data Integrity Data independence

Normalization is the process of decomposing the attributes in an application,

which results in a set of tables with very simple structure. The purpose of

normalization is to make tables as simple as possible. Normalization is carried out in

this system for the following reasons.

To structure the data so that there is no repetition of data, this helps insaving.

To permit simple retrieval of data in response to query and report request. To simplify the maintenance of the data through updates, insertions,

deletion.

To reduce the need to restructure or reorganize data which newapplication requirements arise?


28/63

Relational Database Management System (RDBMS):

A relational model represents the database as a collection of relations.

Each relation resembles a table of values or file of records. In formal relational model

terminology, a row is called a tuple, a column header is called an attribute and the

table is called a relation. A relational database consists of a collection of tables, each

of which is assigned a unique name. A row in a tale represents a set of related values.

Relations, Domains & Attributes:

A table is a relation. The rows in a table are called tuples. A tuple is an ordered

set of n elements. Columns are referred to as attributes. Relationships have been set

between every table in the database. This ensures both Referential and Entity

Relationship Integrity. A domain D is a set of atomic values. A common method of

specifying a domain is to specify a data type from which the data values forming the

domain are drawn. It is also useful to specify a name for the domain to help in

interpreting its values. Every value in a relation is atomic, that is not decomposable.

Relationships:

Table relationships are established using Key. The two main keys of primeimportance are Primary Key & Foreign Key. Entity Integrity and

Referential Integrity Relationships can be established with these keys.

Entity Integrity enforces that no Primary Key can have null values. Referential Integrity enforces that no Primary Key can have null values. Referential Integrity for each distinct Foreign Key value, there must exist a

matching Primary Key value in the same domain. Other key are Super Key

and Candidate Keys.

Relationships have been set between every table in the database. Thisensures both Referential and Entity Relationship Integrity.

Normalization:

As the name implies, it denoted putting things in the normal form. The

application developer via normalization tries to achieve a sensible organization of

data into proper tables and columns and where names can be easily correlated to the

data by the user.


29/63

29

Normalization eliminates repeating groups at data and thereby avoids data

redundancy which proves to be a great burden on the computer resources. This

includes:

Normalize the data. Choose proper names for the tables and columns. Choose the proper name for the data.

First Normal Form:

The First Normal Form states that the domain of an attribute must include only

atomic values and that the value of any attribute in a tuple must be a single value from

the domain of that attribute. In other words 1NF disallows relations within relations

or relations as attribute values within tuples. The only attribute values permitted by

1NF are single atomic or indivisible values.

The first step is to put the data into First Normal Form. This can be donor by

moving data into separate tables where the data is of similar type in each table. Each

table is given a Primary Key or Foreign Key as per requirement of the project. In this

we form new relations for each monatomic attribute or nested relation. Thiseliminated repeating groups of data.

A relation is said to be in first normal form if only if it satisfies the constraints that

contain the primary key only.

Second Normal Form:

According to Second Normal Form, for relations where primary key contains

multiple attributes, no non key attribute should be functionally dependent on a part of

the primary key.

In this we decompose and setup a new relation for each partial key with its

dependent attributes. Make sure to keep a relation with the original primary key and

any attributes that are fully functionally dependent on it. This step helps in taking out

data that is only dependant on apart of the key.


30/63

30

A relation is said to be in second normal form if and only if it satisfies all the first

normal form conditions for the primary key and every non-primary key attributes of

the relation is fully dependent on its primary key alone.

Third Normal Form:

According to Third Normal Form, Relation should not have a non key

attribute functionally determined by another non key attribute or by a set of non key

attributes. That is, there should be no transitive dependency on the primary key.

In this we decompose and set up relation that includes the non key attributes that

functionally determines other non key attributes. This step is taken to get rid of

anything that does not depend entirely on the Primary Key.

A relation is said to be in third normal form if only if it is in second normal form

and more over the non key attributes of the relation should not be depend on other non

key attribute.

5.7 INPUT DESIGN

The input design is the link between the information system and the user.

It comprises the developing specification and procedures for data preparation and

those steps are necessary to put transaction data in to a usable form for processing can

be achieved by inspecting the computer to read data from a written or printed

document or it can occur by having people keying the data directly into the system.

The design of input focuses on controlling the amount of input required, controlling

the errors, avoiding delay, avoiding extra steps and keeping the process simple. The

input is designed in such a way so that it provides security and ease of use with

retaining the privacy. Input Design considered the following things:

What data should be given as input? How the data should be arranged or coded? The dialog to guide the operating personnel in providing input. Methods for preparing input validations and steps to follow when error

occur.

OBJECTIVES

Input Design is the process of converting a user-oriented description of

the input into a computer-based system. This design is important to avoid errors in the

data input process and show the correct direction to the management for getting correct

information from the computerized system.

It is achieved by creating user-friendly screens for the data entry to

handle large volume of data. The goal of designing input is to make data entry easier

and to be free from errors. The data entry screen is designed in such a way that all the

data manipulates can be performed. It also provides record viewing facilities.

When the data is entered it will check for its validity. Data can be entered

with the help of screens. Appropriate messages are provided as when needed so that

the user will not be in maize of instant. Thus the objective of input design is to create

an input layout that is easy to follow.


40/63

40

5.8 OUTPUT DESIGN

A quality output is one, which meets the requirements of the end user

and presents the information clearly. In any system results of processing are

communicated to the users and to other system through outputs. In output design it is

determined how the information is to be displaced for immediate need and also the

hard copy output. It is the most important and direct source information to the user.

Efficient and intelligent output design improves the systems relationship to help user

decision-making.

Designing computer output should proceed in an organized, well thoughtout manner; the right output must be developed while ensuring that each

output element is designed so that people will find the system can use

easily and effectively. When analysis design computer output, they should

Identify the specific output that is needed to meet the requirements.

Select methods for presenting information. Create document, report, or other formats that contain information

produced by the system.

The output form of an information system should accomplish one or more of the

following objectives.

Convey information about past activities, current status or projections ofthe Future.

Signal important events, opportunities, problems, or warnings. Trigger an action. Confirm an action.

CHAPTER 6

SYSTEM TESTING

Software Testing is the process of executing software in a controlled manner,

in order to answer the question Does the software behave as specified?. Software

testing is often used in association with the terms verification and validation.

Validation is the checking or testing of items, includes software, for conformance and

consistency with an associated specification. Software testing is just one kind of

verification, which also uses techniques such as reviews, analysis, inspections, and

walkthroughs. Validation is the process of checking that what has been specified is

what the user actually wanted.

Validation : Are we doing the right job?

Verification : Are we doing the job right?

Software testing should not be confused with debugging. Debugging is the

process of analyzing and localizing bugs when software does not behave as expected.

Although the identification of some bugs will be obvious from playing with the

software, a methodical approach to software testing is a much more thorough means

for identifying bugs. Debugging is therefore an activity which supports testing, but

cannot replace testing.

Other activities which are often associated with software testing are static

analysis and dynamic analysis. Static analysis investigates the source code of

software, looking for problems and gathering metrics without actually executing the

code. Dynamic analysis looks at the behavior of software while it is executing, to

provide information such as execution traces, timing profiles, and test coverage

information.

Testing is a set of activity that can be planned in advanced and conducted

systematically. Testing begins at the module level and work towards the integration of

entire computers based system. Nothing is complete without testing, as it vital success


42/63

42

of the system testing objectives, there are several rules that can serve as testing

objectives.

They are

Testing is a process of executing a program with the intend of finding anerror.

A good test case is one that has high possibility of finding an undiscoverederror.

A successful test is one that uncovers an undiscovered error.If a testing is conducted successfully according to the objectives as stated above, it

would uncovered errors in the software also testing demonstrate that the softwarefunction appear to be working according to the specification, that performance

requirement appear to have been met.

There are three ways to test program.

For correctness For implementation efficiency

For computational complexityTest for correctness are supposed to verify that a program does exactly what it was

designed to do. This is much more difficult than it may at first appear, especially for

large programs.

6.1 TEST PLANS

A test plan implies a series of desired course of action to be followed in

accomplishing various testing methods. The Test Plan acts as a blue print for theaction that is to be followed. The software engineers create a computer program, its

documentation and related data structures. The software developers is always

responsible for testing the individual units of the programs, ensuring that each

performs the function for which it was designed. There is an independent test group

(ITG) which is to remove the inherent problems associated with letting the builder to

test the thing that has been built. The specific objectives of testing should be stated in

measurable terms. So that the mean time to failure, the cost to find and fix the defects,


43/63

43

remaining defect density or frequency of occurrence and test work-hours per

regression test all should be stated within the test plan.

The levels of testing include:

Unit testing Integration Testing Data validation Testing Output Testing

6.1.1 UNIT TESTING

Unit testing focuses verification effort on the smallest unit of software

design the software component or module. Using the component level design

description as a guide, important control paths are tested to uncover errors within the

boundary of the module. The relative complexity of tests and uncovered scope

established for unit testing. The unit testing is white-box oriented, and step can be

conducted in parallel for multiple components. The modular interface is tested toensure that information properly flows into and out of the program unit under test.

Tests of data flow across a module interface are required before any other test

is initiated. If data do not enter and exit properly, all other tests are moot. Selective

testing of execution paths is an essential task during the unit test. Good design dictates

that error conditions be anticipated and error handling paths set up to reroute or

cleanly terminate processing when an error does occur. Boundary testing is the last

task of unit testing step. Software often fails at its boundaries.

Unit testing was done in Sell-Soft System by treating each module as separate

entity and testing each one of them with a wide spectrum of test inputs. Some flaws in

the internal logic of the modules were found and were rectified.

6.1.2 INTEGRATION TESTING

Integration testing is systematic technique for constructing the program

structure while at the same time conducting tests to uncover errors associated with


44/63

44

interfacing. The objective is to take unit tested components and build a program

structure that has been dictated by design. The entire program is tested as whole.

Correction is difficult because isolation of causes is complicated by vast expanse of

entire program. Once these errors are corrected, new ones appear and the process

continues in a seemingly endless loop.

After unit testing in Sell-Soft System all the modules were integrated to test

for any inconsistencies in the interfaces. Moreover differences in program structures

were removed and a unique program structure was evolved.

6.1.3VALIDATION TESTING OR SYSTEM TESTING

This is the final step in testing. In this the entire system was tested as a whole

with all forms, code, modules and class modules. This form of testing is popularly

known as Black Box testing or System tests.

Black Box testing method focuses on the functional requirements of the

software. That is, Black Box testing enables the software engineer to derive sets of

input conditions that will fully exercise all functional requirements for a program.

Black Box testing attempts to find errors in the following categories; incorrector missing functions, interface errors, errors in data structures or external data access,

performance errors and initialization errors and termination errors.

6.1.4 OUTPUT TESTING OR USER ACCEPTANCE TESTING

The system considered is tested for user acceptance; here it should satisfy the

firms need. The software should keep in touch with perspective system; user at the

time of developing and making changes whenever required. This done with respect tothe following points

Input Screen Designs, Output Screen Designs, Online message to guide the user and the like.

The above testing is done taking various kinds of test data. Preparation of test data

plays a vital role in the system testing. After preparing the test data, the system under

study is tested using that test data. While testing the system by which test data errors


45/63

45

are again uncovered and corrected by using above testing steps and corrections are

also noted for future use.

Validation Checking:

At the culmination of integration testing, software is completely assembled as

a package; interfacing errors have been uncovered and corrected, and a final series of

software test-validation checks may begin. Validation can be defined in many ways,

but a simple definition (Albeit Harsh) is that validation succeeds when software

functions in a manner that can be reasonably expected by a customer. Software

validation is achieved through a series of black-box tests to be conducted and a test

procedure defines specific test cases that will be used in attempt to uncover errors inconformity with requirements. Both the plan and procedure are designed to ensure

that all functional requirements are satisfied; all performance requirements are

achieved; documentation is correct and human Engineered and other requirements

are met. Once the application was made free of all logical and interface errors ,

inputting dummy data to ensure that the software developed satisfied all the

requirements of the user did validation checks .However , the data are created with the

intent of determining whether the system will process them correctly .

In the proposed system, if the clients click the send button after selecting a file

from his file list, then the system will show the confirmation message for sending

files. Similarly if a client makes an attempt to download a file from the server file list,

then also the system will show the confirmation message for downloading. This is

how the data validations were made in the proposed system.

CHAPTER 7

SYSTEM IMPLEMENTATION

INTRODUCTION

Implementation is the stage of the project where the theoretical design is

turned into a working system. It can be considered to be the most crucial stage in

achieving a successful new system gaining the users confidence that the new system

will work and will be effective and accurate. It is primarily concerned with user

training and documentation. Conversion usually takes place about the same time the

user is being trained or later. Implementation simply means convening a new system

design into operation, which is the process of converting a new revised system design

into an operational one.

Implementation is the stage of the project where the theoretical design is tuned

into a working system. At this stage the main work load, the greatest upheaval and

the major impact on the existing system shifts to the user department. If the

implementation is not carefully planned and controlled it can create chaos and

confusion.

Implementation includes all those activities that take place to convert from the

existing system to the new system. The new system may be a totally new, replacing

an existing manual or automated system or it may be a modification to an existing

system. Proper implementation is essential to provide a reliable system to meet

organization requirements. The process of putting the developed system in actual use

is called system implementation. This includes all those activities that take place to

convert from the old system to the new system. The system can be implemented only

after through testing is done and if it is found to be working according to the

specifications. The system personnel check the feasibility of the system.


47/63

47

The more complex the system being implemented, the more involved will be

the system analysis and design effort required to implement the three main aspects:

education and training, system testing and changeover. The implementation state

involves the following tasks:

Careful planning. Investigation of system and constraints. Design of methods to achieve the changeover. Training of the staff in the changeover phase.

7.1 IMPLEMENTATION PROCEDURES

Implementation of software refers to the final installation of the package in its

real environment, to the satisfaction of the intended uses and the operation of the

system. In many organizations someone who will not be operating it, will commission

the software development project. In the initial stage people doubt about the software

but we have to ensure that the resistance does not build up, as one has to make sure

that

The active user must be aware of the benefits of using the new system. Their confidence in the software is built up. Proper guidance is imparted to the user so that he is comfortable in

using the application.

Before going ahead and viewing the system, the user must know that for

viewing the result, the server program should be running in the server. If the server

object is not up running on the server, the actual process wont take place.

7.1.1 User Training

User training is designed to prepare the user for testing and converting the

system. To achieve the objective and benefits expected from computer based system,

it is essential for the people who will be involved to be confident of their role in the

new system. As system becomes more complex, the need for training is more

important.


48/63

48

7.1.2 Training on the Application Software

After providing the necessary basic training on computer awareness the user

will have to be trained on the new application software. This will give the underlying

philosophy of the use of the new system such as the screen flow, screen design type of

help on the screen, type of errors while entering the data, the corresponding validation

check at each entry and the ways to correct the date entered. It should then cover

information needed by the specific user/ group to use the system or part of the system

while imparting the training of the program on the application. This training may be

different across different user groups and across different levels of hierarchy.

7.1.3 Operational Document

Once the implementation plan is decided, it is essential that the user of the

system is made familiar and comfortable with the environment. Education involves

right atmosphere and motivating the user. A documentation providing the whole

operations of the system is being developed in such a way that the user can work with

it in well consistent way. The system is developed user friendly so that the user can

work the system from the tips given in the application itself. Useful tip and guidance

is given inside the application itself to help the user.

7.1.4 System Maintenance

Maintenance is the enigma of system development. The maintenance phase of

the software cycle is the time in which a software product performs useful work.

After a system is successfully implemented, it should be maintained in a proper

manner.

System maintenance is an important aspect in the software development life

cycle. The need for system maintenance is for it to make adaptable to the changes in

the system environment.

Software maintenance is of course, far more than Finding Mistakes.

Maintenance may be defined by describing four activities that are undertaken after a

program is released for use.

CHAPTER 8

CONCLUSION & FUTURE ENHANCEMENT

8.1 CONCLUSION

The project titled as Online Crime file Management System is a web

based application. This software provides facility for reporting online crimes,

complaints, missing persons, show most wanted person details mailing as well as

chatting. This software is developed with scalability in mind. Additional modules can

be easily added when necessary. The software is developed with modular approach.

All modules in the system have been tested with valid data and invalid data and

everything work successfully. Thus the system has fulfilled all the objectives

identified and is able to replace the existing system.

The project has been completed successfully with the maximum satisfaction

of the organization. The constraints are met and overcome successfully. The system is

designed as like it was decided in the design phase. The project gives good idea on

developing a full-fledged application satisfying the user requirements.

The system is very flexible and versatile. This software has a user-friendly

screen that enables the user to use without any inconvenience. Validation checks

induced have greatly reduced errors. Provisions have been made to upgrade the

software. The application has been tested with live data and has provided a successful

result. Hence the software has proved to work efficiently.

8.2 SCOPE FOR FUTURE ENHANCEMENT

In future we can use Image recognition instead of using heterogeneous

database more over High speed, accuracy and non-redundant data are the main

advantages of the proposed system. In the proposed system the user is provided with a

choice of data screen, which are similar in formats to the source documents. Data

entry errors can be minimized through validity checks. After the verification only the

data are placed the permanent database.
