    - A cluster provides an optional method of storing table data.

    - A cluster is made up of a group of tables that share the same data blocks.

    - The tables are grouped together because they share common columns and are often used together.

    - Use clusters for tables for which the following conditions are true:

    1. The tables are primarily queried--that is, tables that are not predominantly inserted into or updated.

    2. Records from the tables are frequently queried together or joined.
