    摘要: The present invention generally is directed to a system, method and article of manufacture for accessing data independent of the particular manner in which the data is physically represented. In one embodiment, a data repository abstraction layer provides a logical view of the underlying data repository that is independent of the particular manner of data representation. In one embodiment, the data repository abstraction layer specifies a location of data in a repository and a method for accessing the data. A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs translation of an abstract query into a form that can be used against a particular physical data representation.

    摘要: A system, method and article of manufacture are provided for accessing data independent of the particular manner in which the data is physically represented. In one embodiment, a plurality of data repository abstractions provide different logical views of the same underlying data repository. The plurality of data repository abstractions may each be associated with different users, thereby exposing a different set of data to each user. A runtime component performs translation of abstract queries into a form that can be used against a particular physical data representation.
