We want to analyze and design a software system using the object oriented methodology for al bank. The developed system will allow the Costumers holding accounts (checking, business and saving) in the bank to make online transactions (Withdrawal, money transfer, balance inquiry ..etc) without need to go to a bank center. The same system is used by the bank tellers at the banking center to do regular transaction for each client who go to the banking center. The bank has several centers all over the country but each some has specific capabilities (availability of ATM machine, international money transfer, etc..). The banking system is able to identify is employees as well as its customers. The system allows the clients to request for loans. The system keeps track of each loan and its payments. The client can associate his monthly bills to his checking account. The bill is automatically deduced from the account. Monthly payments can be also associated to any client bank account so they are automatically deposited into his account. A client holding a business account can request a checkbook. 1- Extract from the system textual description the possible objects 2- Draw a class diagram.
