ABSTRACT

Database is an organized collection of information, data, or citations stored in electronic format that can be searched for specific information or records by techniques specific to each database. Database program is a program used to electronically collect data, process it and also store it for future use.

This database program implements the techniques of database normalization. Normalization is the process of efficiently organizing data in a database. There are two goals of the normalization process: eliminating redundant data (for example, storing the same data in more than one table ) and ensuring data dependencies make sense (only storing related data in a table). Both of these are worthy goals as they reduce the amount of space a database consumes and ensure that data is logically stored. The program is more on a religious group. The sore purpose of this program is to enhance and facilitate the church approach to information collection and storage for future use.

ORGANIZATION OF WORK

This project work is primarily designed to give an insight to Database Design Methodology and Tool for Information Systems.

Chapter one talks about introduction to database program, study of problem and objectives as well as definition of the scope.

Chapter two comprises the literature review. Chapter three gives the detailed information about the existing (old) system, while chapter four and five deals with the design and implantation of new system.

Chapter six document the project work, while chapter seven summaries, conclusion and suggestions were made.
