ABSTRACT:
The present invention is generally directed to a system, method and article of manufacture for accessing 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. For each successive query, the data repository abstraction layer is replaced or redefined to provide a restricted logical view of the underlying data repository.
