The Relational Model,n as the data structure. After we present the notion of a relation, we present other fundamental concepts such as candidate key, primary key and foreign key. Integrity rules such as the entity integrity rule and the referential integrity rule are presented. We conclude this chapter with a brief introduction to relational operations.
