Write the problem definition and analyze the feasibility of the system

To facilitate depositors, a bank intends to develop a computer savings system. The deposit slip or withdrawal form that the depositor fills in is entered by the clerk, and if it is a deposit, the system records the depositor's name, address, deposit type, deposit date, interest rate and other information, and prints out the deposit slip to the depositor; if it is a withdrawal, the system calculates the interest and prints the interest list to the depositor.

A: The so-called problem definition, is to solve what problem? The system starts from two aspects. 1) deposit, depositors fill in the deposit slip, and then to the clerk type system, while the system also records the depositor's name, address (or telephone number), identification number, deposit type, deposit date, interest rate and other information, completed by the system to print the deposit slip to the depositors. 2) withdrawals, depositors fill out a withdrawal slip, and then handed over to the clerk, the clerk to enter the amount of money into the system and require depositors to enter a password to confirm identity, check the password is correct after the system calculates interest and prints the interest list to depositors. Then, to study the feasibility of this system, in order to meet the requirements of users, the system must be able to quickly feedback users, to the user input information to make the fastest processing, so it needs a lot of main memory capacity, as well as strong database support. Because the user is a wide range of savings user base, so the system needs strong security to support.
