Abstract
A database system includes database software to receive a query specifying a join of plural base tables, and to determine whether a foreign key and primary key relationship exists between join columns specified by the query and a materialized view definition. Based on the existence of the foreign key and the primary key relationship between join columns specified by the query and the materialized view definition, the database software determines that a result for the received query is to be computed from the materialized view.
