Abstract: Introduction Relational database systems provide a powerful abstraction mechanism: any query, since it returns a relation, can be used to define a view, that becomes a derived (or virtual) relation. Views are defined by a statement such as "define view <name> as <query>." Views can be used to tailor the global database schema. . Query formulation is simplified, if frequent subexpressions are predefined. . Application programs are insulated from changes to the underlying schema. .... (Update)
