Consider the following case study and draw level-0 data flow diagram. Habib Bank Limited provides car and home loans to its banking customers. Initially, a potential loan customer meets with a bank officer, requests a loan for a certain amount and period, and completes a loan application. Next, the bank officer determines the customers credit standing, the type of loan required, and available interest rates. While the bank officer can authorize car loans for credit worthy customers, a loan committee must approve all home loans.
