ABSTRACT:
A method for modeling a database management system involving receiving a query, computing a hit rate value associated with a cache, wherein the hit rate value is computed using a counter group, comparing the hit rate value to a predetermined value to obtain a result, providing a reply to the query if the result is a hit, incrementing a counter in the counter group when the cache is not full and proceeding to a next cache if the result is a miss, and providing a diagnostic output for the database management system.
