2. Understanding Ingres Star Architecture : Distributed Database : Catalogs
Share this page                  
When you create a distributed database, Ingres Star creates catalogs to coordinate access to all the data. The catalogs are a collection of tables that store information about the distributed database. They describe every local database that is a component of the distributed database, as well as the distributed database’s objects. For a complete description of the catalogs, see the chapter “Ingres Star Catalogs” and the appendix “Standard Catalog Interface.”
