• A new concurrency control mechanism in a coupled Knowledge Base Management System is presented. The system combines a multi-users logic programming system and a Relational Database Management System. The proposed mechanism, Query-Rule Locking, is inspired by two-phase locking, but it uses the concept of`relate to' to detect and handle new conflicting problems that arise when multi-users execute Horn clause transactions that access a very large shared knowledge base concurrently. In addition, the number of objects to be locked is minimized by using the `relate-cover' concept to increase the throughput of transaction execution. This method has been proved to guarantee serializability as well as correctness.
