Consider a banking system. The bank manager can log into the system to add and delete customer accounts. In addition, he can modify customer details. The cashier logs onto the system and can update balance details when the customer withdraws/deposits an amount from his account. When an account is closed an e- mail to the customer is generated and sent automatically. The customer can log onto the system and lodge complaints if any. In addition, he can check his account balance. The complaints from the customer are viewed by the manager and the status of the complaint is maintained by the system. The complaints are handled manually, and the manager updates the complaint status in the system once processing is done. An e-mail to the customer is again automatically generated and sent notifying the status of his complaint.
