The first assignment will cover E/R modelling (Chapter 4).We will consider the relational model, upon which SQL is based, (Ch. 2) only after we understand Entities and Relationships.

This top-down approach will avoid the problems mentioned in Ch. 3. We will then proceed with SQL, the database language.
