Semantic query optimization is a process of using integrity constraints and other semantic knowledge to transform a query into another equivalent one. This paper describes one approach to semantic query optimization based on precompiling the integrity constraints and gathering some information after processing a query that might be helpful for successive queries. Once ICs are compiled, all the queries will use the compiled form of ICs for optimization which will reduce the optimization time significantly. Knowledge acquired during the processing of a query is stored as temporary ICs or as control knowledge which can guide the search process of the database for future queries.
