PERK is a storage system that loads Knowledge Bases (KB) from the Oracle DBMS. Its current limitation is the inability to do client-side memory flushing out. In this paper, the authors 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. The basic design is based on Open Knowledge Base Connectivity (OKBC), which is an Application Programming Interface (API) for accessing Knowledge Representation systems (KRS).
