Introduction
A database forms a significant constituent of the information system, particularly in business-oriented systems. As a consequence, the process of developing database system is a component of system development. The division of the development process into a collection of steps or phases is a core feature of software engineering. Each of the phases focuses on a single aspect of the development.
