Abstract
In a data communication system a first controller (102) selectively retrieves data from a database (316) in a second controller (106). Data corresponding to a plurality of entities is programmed (602) into the database. The data includes a plurality of parameters for each of the plurality of entities. Ones of the plurality of parameters are selectively defined (604) to belong to parameter groups in accordance with a predetermined grouping plan. The first controller generates (612) a request for the data corresponding to one of the plurality of entities from the database, the request further indicating a desired one of the parameter groups. The second controller returns (620) the desired one of the parameter groups corresponding to the one of the plurality of entities, in response to the request.
