Structures: Structures are well-defined objects which store the data of a database. Structures and the data contained inside them can be manipulated through operations.

Operations: Operations are clearly described actions which permit users to manipulate the data and structures of a database. The operations on a database must adhere to a pre- described set of integrity rules.

Integrity Rule: Integrity rules are the laws in which govern those operations is permitted on the data and structures of a database. Integrity rules protect the data and the structures of a database.
