View in this approximate order
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.

      Second client program: To modify your database - May be in C, C++, Python, or PHP

Client should identify her or himself, and client (or clerk) see a list of things that can be ordered. Orders to be entered into the database. (or the equivalent). This can be a GUI or web application if you wish.
