US Patent 7836070 Automatic event registration during query execution

In one aspect, a computer-implemented method may provide evaluation of a query based on query-specific event handlers. The method may include receiving a query. Moreover, one or more objects and aspects of the objects may be determined based on the received query. The objects and aspects may be registered with event handlers to monitor the objects and aspects. The received query may be evaluated, when at least one of the event handlers indicates a change to at least one of the objects and the aspects. Other event handlers may be registered, when at least one of the event handlers indicates the change. Related systems, apparatus, methods, and/or articles are also described.
