A Cluster is a schema object that contains data from one or more tables, all of which have one or more columns in common. Oracle stores together all the rows from all the tables that share the same cluster key.


Cluster Editor allows you to define cluster properties. It opens automatically when you create a new cluster and is available on editing an existing one.


To open a cluster in Cluster Editor, double-click it in the DB Explorer tree.
