Structure of Relational Database

  1. A relational database consists of a collection of tables, each having a unique name.

    A row in a table represents a relationship among a set of values.

    Thus a table represents a collection of relationships.

  2. There is a direct correspondence between the concept of a table and the mathematical concept of a relation. A substantial theory has been developed for relational databases.
