Beschreibung
Zusammenfassung:	A database system supports live record invalidation at one or more client systems. As client system request database resources such as data objects from the database system, the database system registers entries at an object user map that indicates which objects are active and what client systems are viewing such objects. If one of the objects is changed, the database server utilizes the object user map to identify other client systems that are viewing the changed record. The database server may transmit change event indications to the client systems, and the client systems can request the updated data corresponding to the updated object.
