Databases and Relations

Databases and Relations. Let us take a look at a type of database representation that is based on relations, namely the relational data model. A database consists of n-tuples called records , which are made up of fields . These fields are the entries of the n-tuples.

Properties of Relations

Properties of Relations. We will now look at some useful ways to classify relations. Definition: A relation R on a set A is called reflexive if (a, a)?R for every element a?A. Are the following relations on {1, 2, 3, 4} reflexive?. R = {(1, 1), (1, 2), (2, 3), (3, 3), (4, 4)}. No.
