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. Everyone wants his/her work to be done by computer automatically and displaying the result for further manipulations.
This term paper project is just an application of the language C in developing softwares. This is the program for keeping records of the salary ,that is the entire details of the customer ,savings ,how much money he/she can deposit and withdraw from the bank, to open the new account ,create a new account ,display all account holders, balance enquiry etc.
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

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:-
This project can be implement only at small bank branches. It cannot be used for large scale bank purposes.
