chapter 5The Database Life Cycle
Before we delve into the particulars of database design, it is useful to understand the framework in which the design takes place. The life cycle of a database (or computer system) is the term we use for all the events that take place between the time we first recognize a need for a database, continuing through its development and deployment, and finally ending with the day it is retired from service.
