Abstract: The present approach improves the query performance of a database in a manner that is transparent to a user. In one aspect, this approach creates separate partition tables that are not directly accessible to a user of the database. A client-facing aspect of the database is a logical model which may correspond to a single, main table with which the user interacts. Thus, queries or operations may be generated on the client side in the context of the logical model. A database or query layer can then, transparent to the user, translate the user generated requests into query language that addresses the proper partitions to generate a result set or otherwise perform a database operation.
