US Patent 7991788 Abstract data model filters

The present invention generally is directed to methods, articles of manufacture and systems for presenting, to a user, a limited subset of fields of an underlying base data model. The limited subset of fields may be generated by applying one or more filters to select, exclude and/or modify the fields of the base data model. The base data model may contain abstract representations of fields in a data repository and may, therefore, serve as a data definition framework allowing data from the fields to be accessed independent of the particular manner (e.g., SQL, XML, etc.) in which the data is physically represented in the data repository.
