A method and database system for improving the operational performance of a database. The method includes determining whether an instruction or operatio n (22) adds information to or removes information from the database. For an ad d operation, information is first added to an 'out' table (23) used to retriev e objects or entries before the database is actually updated. For a removed operation, information is first removed from an 'in' table (25) used to find objects in the database. Preferably, for an add operation, the information i s added to the 'in' table (24) after the 'out' table, and for a remove operation, information is preferably removed from the 'out' table (26) after the 'in' table. |
