Abstract

The author introduces RPL (the relational production language) and explores the opportunities it presents for expert database systems. RPL is a language for developing expert systems that bridges the gap between expert systems and database systems. The author also introduces an expert database system architecture based on the RPL approach. Specifically, she proposes a two-level database hierarchy in which the systems´ outer level comprises conventional databases and the inner level contains an RPL interpreter using a memory-resident relational database to replace working memory. The system then uses RPL rules to express and control data staging between levels. The author also discusses related work, describes ongoing research, and presents her conclusions.<>
