An integration component assists in the integration of information distribution systems (IDSs). The integration component may help to identify the scope of the systems that are to be integrated using a multi-level top-down approach. The multi-level top-down approach may include five levels: a system software level, a business process level, a business rule level, an interface function level, and a data level. A fault detection component may then check the identified systems to identify potential faults. This check can be performed by representing the business rules as a Transition-Directed-Graph (TDG) and then processing the TDG using generic depth-first search (DFS)-based algorithms.
