INTRODUCTION

In the existing system, most of the records are maintained on paper. It becomes very inconvenient to modify the data. In the existing system, here is a possibility that the same data in different registers may have different values which means the entries of the same data do not match. This inconsistent state does not supply the concrete information which poses a problem in the case information related to particular search record.Our project is very useful. User is no longer required to check his register in search of records, as now it can be searched over the software by choosing some options. The user need not to type in most of the information. He/she is just required to enter the desired options. On the whole it liberates the user from keeping lengthy manual records. In a nutshell, it abates the work load of an organization.

In today’s world, no one likes to perform calculations on calculator or manually when computer is there. Every one wants his/her work to be done by computer automatically

and displaying the result for further manipulations.

PROPOSED SYSTEM

The following documentation is a project the “Name of the term paper allotted”. It is a detailed summary of all the drawbacks of the old system and how the new proposed system overcomes these shortcomings. The new system takes into account the various factors while designing a new system. It keeps into the account the Economical bandwidth available for the new system. The foremost thing that is taken care of is the Need and Requirements of the User.

DESCRIPTIONBefore developing software we keep following things in mind that we can develop powerful and quality softwarePROBLEM STATEMENT

o Problem statement was to design a module:o Which is user friendlyo Which will restrict the user from accessing other user’s data.o Which will help user in viewing his data and privileges.o Which will help the administrator to handle all the changes.

FUNCTIONS TO BE PROVIDED:The system will be user friendly and completely menu driven so that the users shall have no problem in using all options.

o The system will be efficient and fast in response.o The system will be customized according to needs.

SYSTEM REQUIRMENTSOperating system: MS Windows XP or Windows VistaLanguage: C LanguageProcessor: Pentium IV ProcessorRAM: 512 MBHard disk: 5 GB

REQUIREMENT ANALYSIS

This process is adopted when management of the system development, Personnel decide that the particular system needs improvement. The system development life cycle is the set of activities, carried out by the analyst, designers and users to develop and implement a system. The systems that are present in the nature follow common life cycle pattern. For example consider the raining system. Initially the rain falls into the river, river flows into sea, the sea water evaporates to form vapors, the vapors form clouds which again bring rain. Similarly consider a man made system initially a system is analyzed, designed and made operational by the efforts of system analysis. After successful operation or a number of users, the system becomes less and less effective by change in the environment. So these changes have to be incorporated in to the system by minor modifications. So the general activities from the life cycle of the system are given below:

Select ion and identification of the system to be studied Preliminary study Defining the system Design and development of the system Implementation of the system

SYSTEM DESIGN

Then we began with the design phase of the system. System design is a solution, a “HOW TO” approach to the creation of a new system. It translates system requirements into ways by which they can be made operational. It is a translational from a user oriented document to a document oriented programmers. For that, it provides the understanding and procedural details necessary for the implementation. Here we use Flowchart to supplement the working of the new system. The system thus made should be reliable, durable and above all should have least possible maintenance costs. It should overcome all the drawbacks of the Old existing system and most important of all meet the user requirements.

TESTING

Testing is the major control measure used during software development. Its basic function is to detect errors in the software. During requirement analysis and design, the output is a document that is usually textual and no executable. After the coding phase, computer programs are available that can be executed for testing purpose. This implies that testing not only, has to uncover errors introduced during coding, but also errors introduced during previous phase. Thus the goal of testing is to uncover the requirements, design and coding errors in the programs. So after testing the outputs of my project are as follows:

** Paste the outputs of your project

FUTURE SCOPE OF THE PROJECT

Our project will be able to implement in future after making some changes and modifications as we make our project at a very low level. So the modifications that can be done in our project are:

In future one change can be done by adding the fingerprints of the persons of which the address is entered.And one more major change which can be done in this project is that to add the snaps of the person of which the address is entered.We can also add or subtract details of the individual.
