Claim One:
1. A computer-implemented method for creating a logical security model based on a physical security model defining user access rights to physical data, the method comprising: for each of the user access rights defined by the physical security model, creating a logical access right definition for a logical model, wherein the logical model comprises a plurality of logical field definitions each comprising a field name, physical field location information identifying a specific field of the physical data and an access method for accessing the specific field of the physical data according to the physical field location information; wherein the access methods of a first portion of the plurality of logical field definitions are of a first type and the access methods of a second portion of the plurality of logical field definitions are of a second type; applying the logical access right definitions to the logical model so that the logical model reflects the user access rights to the physical data; and executing, by operation of one or more computer processors, abstract queries composed on the basis of the logical model.
