DATABASE MANAGEMENT ARCHITECTURE

摘要

An architecture for a database process that can process many large queries simultaneously without creating bottlenecks uses a separate database server process to act as the interface with the processes generating the database queries, and a database engine process to process the queries. The database server receives the query notifications and queues the query structure it then passes the query to the database engine when it becomes available. The present invention allows the database server to service small queries it receives, such as requests for configuration data which are critical, and allows a configuration of multiple database engines to service several large queries simultaneously. The database engine process does not actively receive requests from the database server. Rather, it requests work from the database as it becomes available employing a time-out mechanism when the database engine is idle. According to another aspect of the present invention, the database processes perform their own load balancing.
