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. A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs conversion of an abstract query (i.e., a request for results or a request to modify data) into a form that can be used against a particular physical data representation. Abstract and/or physical queries are transformed according to model entities which define a relationship between logical fields of the data repository abstraction layer.
