PREFACE.
This report aims at introducing the various process involved in Child Adoption Center like Registration of Parents & children, Verifying their Age, Salary, Family members , Guarantor Info , stores details of Activities held for children & also keep Information of Donation given to the trust . This reports depicts only the basic logic used for the software development along with flowcharts so that any render may understand the logic applied. The intricate details of the software have not been introduced in the project.

CHAPTER NO:1 SYSTEM STUDY AND ANALYSIS
SYSTEM STUDY AND ANALYSIS .
Methodology: The way that is followed while carrying on with the development application is as follows: Phase I (Defining a Problem): Defining the problem is one of the important activities of the project. The objective is to define precisely the problem to be solved & thereby determine the scope of the new system. This phase consists of 2 main tasks. The 1st task within this activity is to review the basic needs that originally initiated the project. The 2nd task is to identify, at an abstract or general level, the expected capabilities of the new system. Thus, it helps us to define the goal to be achieved and the boundary of the system. A clear understanding of the problem will help us build a better system & reduce the risk of project failure. It also specifies the resources that have to be made available to the project. Three important factors project goal, project bounds & the resource limit are sometimes called the project’s term of references. The output of this phase consists of project goal, it’s bounds and terms of reference. Phase II (Feasibility Study): The feasibility study proposes one or more conceptual solutions to the problem set for the project. The objective in assessing feasibility is to determine whether a development project has a reasonable chance of success. It helps us to determine the input & output of the system. The following are the criteria that are considered to confirm the project feasibility.
Technical Feasibility: At first it is necessary to check that the proposed system is technically feasible or not and to determine the technology and skill necessary to carry out the project. If they are not available then find out the solution to obtain them. Hardware is already available in the college. Operational Feasibility: The operational feasibility is obtained by consulting with the system users. Check that proposed solution satisfies the users need or not. Software details of the proposed system Front End:- Visual Basic 6.0 Back End:- Microsoft Access Phase III (System Analysis):The phase is detailed appraisal of the existing system. This appraisal includes how the system works and what it does. It also includes finding out in more detail- what are the problems with the system and what user requires from the new system or any new change in system. The output of this phase results in the detail model of the system. The model describes the system functions and data and system information flow. The phase also contains the detail set of user requirements and these requirements are used to set objectives for the new system.
System Study:-It is always necessary to study and recognize the problems of the existing system, which will help in finding out the requirements for the new system. System study helps in finding different alternatives for better solution. The project study basically deals with different operations and steps involved in it. It includes: 1) Data gathering 2) Study of existing system 3) Analyzing problem 4) Studying various documents 5) Feasibility study for further improvements Following are the steps taken during the initial study:
Initially, we collected all the information, which they wanted to store
Then we studied the working of the current system which is done manually. We noted the limitations of that system which motivated them to have a new system.
Then we analyzed the format of the reports generated by that system.
With the help of these documents we got basic ideas about the system as well as input and output of the developed Inventory System.
CHAPTER NO:2 CURRENT SYSTEM AND SHORTCOMINGS OF CURRENT SYSTEM
CURRENT SYSTEM. Initially the center was using the manual resources (small notebooks, people) for the transaction involved in the system. This led more overheads in maintaining the transaction manually. It was a tedious job to log the daily activities of the work in a paper like matching expectations of Parents with child. It was difficult to maintain the details of the children, parent and the details of the guarantor. In order to avoid these manual details and to automate entire process of various kinds of transactions carried out in the center this software is developed. Shortcomings of the current system: The existing system has many drawbacks. Some of them to list are as follows:
Manually matching Expectation of the Parents.
No security of data.
Various kind of registers were maintained to keep
the records
To check the records of past few years then register
has to be gone through to acquire the information.
CHAPTER NO:3 PROPOSED SYSTEM
Proposed System: The proposed system is fully computerised and is developed using Visual Basic (6.0) and Microsoft Access. Advantages of the proposed system: Lot of time is getting saved. Details of the Children, Parents, Guarantors and Sponsorer can be saved in the database. It is possible to easily retrieve information about data which is as long as 10 years old or more (depends on the hard-disk space you have in our system) Limitations of the proposed system: Children age should between one & eight year Only single child can be adopted by a parent There can be a single guarantor for a Parent Parents Annual Income should be more than one lakh
SCOPE OF PROPOSED SYSTEM. The first task was in identifying what part of the system is to be computerized. Some analysis and projection was done. Initially investment would be only to impart on the software and the hardware. The system is simple without complexities. The child adoption process deals with the following aspects Accepting the details from the sponsorer & donors. Maintaining and updating the details of the child & Parent. Maintain the database of the Children , Parent , Guarantors . Automatic Matching Of Expectation of the Parent about child. Maintaining the records of the Adopted Children with their Parents and related guarantor. System is developed in Microsoft Access as backend and Visual Basic 6.0 as front-end. It will provide: 1. More user friendly since visual basic-6.0 is best GUI. 2. Minimization of redundancy in well maintained data. 3. Maximum Data security. 4. Achieve facility.

Conclusion The quality and reliability of the software depends on the result of phases in the system development. The software quality includes the modularity, good documentation, user friendliness, maintainability etc. The software reliability depends on the less chances of failure and enhancements in the system even in stressed situations. As far as my developed system is concerned, we have tried to make the system as user friendly as possible where a layman can handle the system very comfortably. During detail design the system is designed into modules so, it is easy to understand and helpful to the management.
Suggestions for Future : The system is developed by keeping in mind the present conditions and rules. If there are changes in the rules and conditions , system needs maintenance according to the changes.
