Abstract:
1. A computer implemented method for automatically generating abstract representations of one or more physical fields of a data source, the method comprising: collecting information regarding usage of the physical fields; and generating the abstract representations of selected ones of the physical fields based on the collected usage information, so that abstract representations are generated only for selective physical fields whose corresponding collected information satisfies predefined criteria; wherein the abstract representations are logical fields each comprising a logical field name, at least one location attribute identifying a location of the respective physical field, and a reference to an access method describing a manner of exposing physical data contained in the respective physical field; wherein collecting information regarding usage of the physical fields comprises gathering information regarding at least one of an index, a foreign key, and an application object; wherein collecting information regarding usage of the physical fields comprises gathering information regarding data repository schema; and wherein generating the abstract representations further comprises generating a list of logical field candidates based on the gathered information regarding data repository schema.
