摘要
The present invention is generally directed to a system, method and article of manufacture for modifying data represented abstractly through an abstraction model. In one embodiment, a data repository abstraction layer provides a logical view of an underlying data repository that is independent of the particular manner of data representation. A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs transformation of an abstract query into a form that can be used against a particular physical data representation. The transformation includes ordering physical modification operations according to a physical entity relationships specification to ensure that the physical modification operations are executed in an appropriate order.
