The project entitled >Telecom connection system? deals with fully automated

system used by the Telecom department.

Telecom industry is one of the major sectors, which provides so many services to

their customers such as request for a new connection, change of number, billing etc.

aintaining all these services manually is complicated process.

The main objective of this project is to automate the services provided by

telecom telecom system, by which customer can use all the services online.

The project has been divided into four modules.

1. $pplications2. "ntries

*. "nquiries

. !omplaints

The Applications module provides following services.

• $ customer can apply for a new telephone connection by filling the form.

• ;e can request for transferring phone connection to another location.

• ;e can modify the mode of bill payment details.

• ;e can also cancel his phone connection.

The Entries module provides following services.

• &f the customer requested for change of telephone number, here if we

enter the old number, it will display the new number.

The Enquiries module provides following services.

• The customer can ma@e a request about his bill.

2.SYSTE ANA!YSIS


5/64

system analysis first stage according to System (evelopment -ife !ycle model. This

System $nalysis is a process that starts with the analyst.

$nalysis is a detailed study of the various operations performed by a system and

their relationships within and outside the system. ne aspect of analysis is defining the

boundaries of the system and determining whether or not a candidate should consider

other related systems. (uring analysis, data is collected from the available files, decision

points, and transactions handled by the present system.

-ogical system models and tools are used in analysis. Training, eCperience, and

common sense are required for collection of the information needed to do the analysis.

2."E#istin$ S%stem

The eCisting system is a manual one where the entrant has to go to the Telecom

!onncetion System and get details of the company for getting the new connection. ;ere

it is getting a tedious one for the user to go and manually register with it. $nd in the

process only a few users are ta@e the connection. To over come this they have proposed

for the online !onnection.

2.2&ro'lem Statement

The previous system was an manual system. So, the system is not available to all

globally. To ma@e the system available globally, it is now proposed to be web enabled.

&n the eCisting manual process entrants can not get the information of all the

telecom system where by registering with Telecom !onnection System they can get the

updated share values and also since the registration process is automiDed, participation in

!onnection is easy to the entrants.

2.(&ropose) S%stem


6/64

The proposed system is the online registration of the entrants with the company.

0y atomiDing this !onnection process, the entrants enjoy the facility to participate from

anywhere. "ntrants can also get the information online about all the telecom system. 0y

this process the user can get all the information of the !onnection process from where

ever he want as there is no need for him to come to the office and register for !onnection.

Thus the proposed system is efficient all the way.


1.$pplications

2."ntries

*."nquiries

.!omplaints

The administrator is responsible for the !onnection process and he maintains allthe information about the telecom system that are offering the !onnection process for

different participants. ;e is also responsible for the registration of different users that are

going to ta@e the !onnection process. The administrator will only offer the !onnection

process and maintain the bill details and everything for the users as well as the telecom

system who are already registered at the !onnection system

&n the )ser odule a new user or an user who is already registered with the

company may be going for !onnection and these persons will @eep their connections by

ta@ing the connection on telecom system. $ user can offer to ta@e new connection

,enquiry, complaints and bill details and every thing on the connection system. The user

can get for the !onnection only for the registered telecom system at the administrator

only.

&n "nquiry module user can @now the details from telecom system regarding his

requirements and another module in user side is complaints i.e ;e can ma@e complaint to

the office if any connection is corrupted. $nd if he want to @now the bill status . These

telecom system has to be registered at the administrator only because he is responsible

for all the !onnection process at the different users.

2.*Requirement Anal%sis

The requirement phase basically consists of three activitiesA

1. 'equirement $nalysis

2. 'equirement Specification

*. 'equirement


8/64

6

• The functions that the software is to perform must be defined.

• The behavior of the software as a consequence of eCternal events must be

defined.

• The models that depict information, function and behavior must be

partitioned in a hierarchical or layered fashion.

• The analysis process must move from essential information to

implementation detail.

2.,Requirement Speci-ication

Speci-ication &rinciples+

Software 'equirements Specification plays an important role in creating quality software

solutions. Specification is basically a representation process. 'equirements are

represented in a manner that ultimately leads to successful software implementation.

'equirements may be specified in a variety of ways. ;owever there are some guidelines

worth followingA :

• 'epresentation format and content should be relevant to the problem

• &nformation contained within the specification should be nested

• (iagrams and other notational forms should be restricted in number and

consistent in use.

• 'epresentations should be revisable.


9/64

So-tare Requirements Speci-ications+

The software requirements specification is produced at the culmination of the

analysis tas@. The function and performance allocated to the software as a part of system

engineering are refined by establishing a complete information description, a detailed

functional and behavioral description, and indication of performance requirements anddesign constraints, appropriate validation criteria and other data pertinent to

requirements.

An outline o- t/e So-tare Requirements Speci-ication+

$ simplified outline can be given for the framewor@ of the specifications. This is

according to the &""" Standards.

2.01easi'ilit% Stu)%

$ll projects are feasible, given unlimited resources and infinite time. 0ut the

development of software is plagued by the scarcity of resources and difficult delivery

rates. &t is both necessary and prudent to evaluate the feasibility of a project at the

earliest possible time.

Three @ey considerations are involved in the feasibility analysis.

Economic 1easi'ilit%+This procedure is to determine the benefits and savings that

are eCpected from a candidate system and compare them with costs. &f benefits outweigh

costs, then the decision is made to design and implement the system. therwise, further

justification or alterations in proposed system will have to be made if it is to have a

chance of being approved. This is an ongoing effort that improves in accuracy at each

phase of the system life cycle.

Tec/nical 1easi'ilit%+


10/64

1=

Technical feasibility centers on the eCisting computer system Fhardware, software,

etc.,G and to what eCtent it can support the proposed addition. &f the budget is a serious

constraint, then the project is judged not feasible.

Operational 1easi'ilit%+

#eople are inherently resistant to change, and computers have been @nown to facilitate

change. &t is understandable that the introduction of a candidate system requires special

effort to educate, sell, and train the staff on new ways of conducting business.

Tec/nical 1easi'ilit%

Technical feasibility spea@s about the eCisting hardware and the software that we

are using and the deviations that we have to ma@e from the eCisting one, as we are

developing the application using java there is no change in the hardware that the

we are using. So we an say that this application is technically feasible as there is

no change in the configuration more over it is cost effective.

Economic 1easi'ilit%

"conomic feasibility tal@s about the benefits that which we get from this project.

;ere with the introduction of this online process we are not only reducing the

time ta@e for the registration of the entrants we even reduce the burden on the

administrator. $s this project is not only reducing the time but also the wor@

burden of the user we say that this product is economically feasible.

Operational 1easi'ilit%


11/64

11

$s this project is a user friendly version there is not much training required for

the people to use. This product is not only ma@ing the tas@ of the administrator

easy but it is reducing the time that is ta@en otherwise. So we say that this product

is operationally feasible.


12/64

(.SYSTE DESIN

The most creative and challenging phase of the life cycle is system design. The

term design describes a final system and the process by which it is developed. &t refers to

the technical specifications that will be applied in implementations of the candidate

system. The design may be defined as >the process of applying various techniques and

principles for the purpose of defining a device, a process or a system with sufficient

details to permit its physical realization”.

The designerEs goal is how the output is to be produced and in what format.

Samples of the output and input are also presented. Second input data and database files

have to be designed to meet the requirements of the proposed output. The processing phases are handled through the program !onstruction and Testing. 5inally, details related

to justification of the system and an estimate of the impact of the candidate system on the

user and the organiDation are documented and evaluated by management as a step toward

implementation.

The importance of software design can be stated in a single word

>Quality” . (esign provides us with representations of software that can be assessed for

quality. (esign is the only way where we can accurately translate a customerEs

requirements into a complete software product or system. 9ithout design we ris@

building an unstable system, that might fail if small changes are made. &t may as well be

difficult to test, or could be one whoEs

quality canEt be tested. So it is an essential phase in the development of a software

product.

The phased lifecycle model represents software lifecycle as a series of successive

activities. This phase requires well:defined input information, processes and results in

well:defined products. The phased lifecycle model consists of following phases.

System definition and a project plan.

The So-tare Desi$n follows analysis. (esign is concerned with its software

components, specifying relationships among components specifying some structure,

maintaining a record of design decisions and providing blueprint implementation phase.

(esign consists of detailed design and $rchitectural design.

The implementation phase of software development involves translation of

design specification into source code, and debugging, documenting and unit testing the

source code. To enhance the quality of the software the methods are structured control

constructs, built in and user defined data types, secure type chec@ing, fleCible scope ruleseCception handling mechanism, concurrency constructs and separates compilation

modules.

needed. $cceptance testing involves planning and eCecution of various tests in order to

demonstrate that the implemented system satisfies the requirement document.

The aintenance phase comes after the acceptance of the product by the

customer and release of the system for production wor@. aintenance activities include

enhancements of capabilities, adaptation of software to new processing environments,

and correction of software bugs.

*.SYSTE TESTIN

Software Testing is a critical element of software quality assurance and represents

the ultimate review of specification, design and coding, Testing presents an interesting

anomaly for the software engineer.

Testin$ O'3ecti6es inclu)e+

1. Testing is a process of eCecuting a program with the intent of finding an error

2. $ good test case is one that has a probability of finding an as yet undiscovered

error *. $ successful test is one that uncovers an undiscovered error

Testin$ &rinciples+

• $ll tests should be traceable to end user requirements

• Tests should be planned long before testing begins

• Testing should begin on a small scale and progress towards testing in large

• "Chaustive testing is not possible

• To be most effective testing should be conducted by a independent third

party

TESTIN STRATERIES

$ Strategy for software testing integrates software test cases into a series of well

planned steps that result in the successful construction of software. Software testing is a

broader topic for what is referred to as

This method as the name suggests, begins construction and testing with atomic

modules i.e., modules at the lowest level. 0ecause the modules are integrated in the

bottom up manner the processing required for the modules subordinate to a given level is

always available and the need for stubs is eliminated.

,."Intro)uction to 8T!

The hyperteCt mar@up language F;T-G is a simple mar@up language. )sed to create

a hyperteCt documents that are portable from one platform to another ;T- documents

are S%- FStandard generaliDed mar@ up languageG documents with generic semantics

that are appropriate for representing information from a wide range of applications. This

specification defines ;T- version *.2. ;T- *.2 aims to capture recommended

practice as of early E7 and as such a replacement for ;T-2.= F'5! 16G.

$ set of instructions embedded in a document is called mar@ up language. These

instructions describe what the document teCt means and how it should loo@ li@e in a

display. ;yper TeCt ar@ )p language F;T-G is the language used to encode 9orld

9ide 9eb documents.

58Y TO USE 8T!

9ebsite is a collection of pages, publications, and documents that reside on web

server. 9hile these pages publications and a document as a formatted in a single format,

you should use ;T- for home page and all primary pages in the site. This will enable

the millions of web users can easily access and to ta@e advantage of your website.

;T- is considered first for formatting any new material you plan to publish on

the web. ;T- documents are platform independent, meaning that they donEt confirm to

any standard. &f they are created properly you can move home page to any server

platform or you can access them with any complaint www browser.

STRUCTURE O1 8T!

;T- elements perform a defined tas@. ;T- uses two types of elements

. "mpty Tags

. !ontainer Tags


51/64

These tags differ because of what they represent. "mpty tags represent formatting

constricts such as line brea@s and horiDontal rules. !ontainer tags define a section of teCt,

formats and dot all of the selected teCt. $ container tag has both a beginning and an

ending.

8T! !AYOUT+

$n ;T- document consists of teCt, which comprises the content of the document and

tags, which, defines the structure, and appearance of the document. The structure of an

;T- document is simple, consists of outer.

KB;T-L

"ach document has a head and body delimited by the K;"$(L and K0(+L tag. The

head is where you give your ;T- document a title and where you indicate other

parameters the browser may use when displaying the document. This includes the teCt for

displaying the teCt. Tag also references special and indicates the hot spots that lin@ your

document to other documents.

!reateting a form usually involves two independent stepsA !reateting the layout

for the form itself and then writing a script program on the server side to process the

formation you get bac@ from a form.

To create a form, +ou use the K5'L tag. &nside the opening and closing

5' tags are each of the individual form elements plus any other ;T- content to

create a layout for that form.

The opening tag of the 5' element usually includes the attributesA "T;(

and $!T&N. The "T;( attributes can be either %"T or #ST which determines

how your form data is sent to the script to process it.

The $!T&N attribute is a pointer to the script that processes the form on the

server side. The $!T&N can be included by a relative path or by a full )'- to a script

on your server or somewhere else. 5or eCample, the following K5'L tag would call a

script called form:name in cgi:bin directory on server www.myservser.com

.

KB5'L

ET8OD ATTRIBUTE+

The other required attribute for the KformL tag sets the methods by which the

browser formEs data to the server for processing. There are two waysA the #ST method

and %"T method. 9ith #ST method, the browser sends the

data in two stepsA the browser first contacts the form:processing server specified in the

action attributes, and once contact is made, sends the data.

The %"T method in the other hand, contacts the form processing server and sends

the form data in a single transaction stepA the browser appends the data to the formEs

action )'-, separated by the question mar@ FOG character.

,.2INTRODUCTION TO SER

Servlets provides a 8ava:0ased solution used to address the problems currently

associated with doing server side programming, including ineCtensible scripting

solutions, platform specific $#&s, and incomplete interfaces. Servlets are objects conform

to a specific interface that can be plugged into a 8ava:based server. Servlets are to the

server:side what applets are to the client:side:object byte codes that can be dynamically

loaded off the net. They differ from applets in that they are faceless objects Fwithout

graphics or a %)& componentG. They serve as platform independent, dynamicallyloadable, plug gable helper byte code objects on the server side that can be used to

dynamically eCtend server:side functionality.

5or eCample, an ;TT# servlet can be used to generate dynamic ;T- content.

9hen you use servlets to do dynamic content you get the following advantagesA

TheyEre faster and cleaner than !%& scripts.

They use a standard $#& Fthe Servlet $#&G

They provide all the advantages of 8ava Frun on a variety of servers without

needing to be rewrittenG
