Data Flow Diagram
Consider the following scenario and create a level 0 diagram.
1. Cooper’s Bank is a commercial lending institution that offers only two banking services. Personal Savings Accounts and Personal Loans. In order to access any of these services you must first be a Customer. To become a customer you must first fill out an application and present it to the customer Service Representative along with your Social Security Card and a current Utility bill. Having collected all the required documentation the Customer Service Representative will issue a Savings Pass Book. This book needs to be submitted when making withdrawals or adding savings to an account. In the case of personal Loans, a person can only borrow up to 80% of the amount that they have in their savings account. To apply for a loan customer is required to fill out a loan application and submit his/her pass book. The account amount is verified and if the savings exceeds 80% the loan is granted immediately. If the loan is granted the customer is given some agreement forms to fill out. These are returned to the customer service representative who files them and issues the money. In the event where the savings amount is less than the required 80%. The customer is denied the loan and is given a pamphlet of good tips on saving.
Having created your level 0 diagram review it to ensure that all required information is present and create a level 1 diagram
