Abstract

An implementation technique for supporting dynamic derived relations within a particular relational DBMS (the RAQUEL II DBMS) is presented. Included is a discussion of the RAQUEL II concepts of permanent and temporary relations, base and derived relations, and explicit and implicit updates. The methods presented here for support of updates in regard to dynamic derived relations take the form of immediate updates. Proofs are presented to show the validity of the update methods.
