About this document
Understanding Relational Database Concepts by Aya Amir is a document available to read on EtoBox.
The document discusses the relational model, which is based on representing data in tables. It defines key terms like relation, attribute, tuple, and domain.

Integrity rules like entity integrity and referential integrity enforce correctness of the data. Views allow querying
