ABSTRACT:
An object-oriented database management system comprises a query processing system for controlling an entire query processing and a database access system which is connected to a database and performs access to the database according to a query from the query processing system. The system performs operation processing, wherein the database access system includes a pointer retrieving part which retrieves, from the database, all pointers to joined keys described in a query conditional expression produced from the query processing system, prior to the join operation, and produces a set of pointers to the joined keys. A join operation part uses the set of pointers produced by the pointer retrieving part to perform the join operation and to evaluate the query conditional expression while acquiring a concatenated key value.
