  7. Example (Taken from 2005 past paper) Draw up a DFD of a very simple Maltese carnumber plate registration system storing registered number plates on a database. Your system should offer the following functionality: • Register (add) a number • Retire (delete) a previously registered number • Check number for validity • Check numbers for uniqueness against a database of assigned numbers • Confirm valid registration www.matthewxuereb.com/uni You should decompose your DFDs to whatever level youdeem necessary to produce PSPECs in any form of pseudo code you wish. All PSPECs must be shown.
