- Introduction
In the previous lectures we looked at conceptual database design
using the ER diagram.
Here we are going to discuss in detail the process of mapping, or
converting and ER design into a relational model. This is the logical
design, or data model mapping, step as shown in the database
design procedure.
We will start by describing how we map an ER diagram into a
relational schema.
