A system of the invention comprises a design module, execution engine, and performance management module. A first computer hosts the design module which enables a user to define attributes, queries, and decision rules transmitted to the execution engine hosted on a second computer remote to the first computer. The second computer can be located at a credit bureau, credit reporting agency, or other data provider. The second computer runs the execution engine to query a data repository with the user-defined attributes and queries, and applies the user-defined decision rules to produce result data transmitted to a third computer hosting the performance management module for monitoring performance of a benefit or offering made with the result data and the corresponding attributes, queries, and decision rules that generated the result data.
