In this paper, we present a new architecture, named PERK-II, which utilizes the object relational capabilities provided by Oracle 8. It can do the client-side buffer management automatically, use object view and complex object retrieval (COR) to reduce network traffic, and push a lot of database functionality from PERK to the Oracle DBMS. So, the system is greatly simplified without sacrificing efficiency. Our basic design is based on open knowledge base connectivity (OKBC), which is an application programming interface (API) for accessing knowledge representation systems (KRS). By far, we have implemented the read-only OKBC operations using the Oracle Call Interface (OCI). Our test results show that the use of the Oracle client-side object cache does not substantially degrade the performance of the system as compared to using a "home grown" in-memory client cache.
