We developed the modeling relation in the preceding chapter as a relation between a natural system and a formal system. This relation was established through an appropriate encoding of the qualities of the natural system into the propositions of the formal system, in such a way that the inferential structure of the latter correspond to the system laws ...

In this chapter we introduce the relational model, a collection of methods and techniques for organizing databases centered on the notion of a relation 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.

In this chapter we describe the Relational Model. This was proposed by Codd, in 1970, long before any relational database system became commercially available. Consequently standards, such as the SQL language, have rapidly emerged in contrast to earlier database systems. The relational model consists of three components: a relation (this being the only
