Definition - What does Cluster Table mean?
Techopedia explains Cluster Table
Prominent features of cluster tables are as follows:
- Native SQL cannot be used on these tables.
- They cannot be directly managed by database system tools.
- Administration of cluster tables is easier because the tables are not created separately, like transparent tables in a database.
- Functionally dependent data stored in cluster tables may be read together, thus reducing access to the database.
- Like pool tables, indexes for non-key fields cannot be created. However, primary or other indexes can be created for a set of fields that are to be key fields.
- Database views, join statements or append statements cannot be used on these tables.
