Abstract: A system of the present invention includes a computer having a processor and a memory, which includes general-purpose components providing support for application tasks processing. In a preferred embodiment, the general-purpose components include a Database Management System (50), a Deductive Database (40), and an Abductive Metainterpreter (30); the latter including an engine for abducing new information from known facts stored in the database. In this fashion, a user may model an environment or domain of interest (e.g., a communication network). Once defined, the environment is automatically maintained by the system of the present invention. In response to a user request for modifying the environment, for example, the system automatically generates transactions which satisfy the request.
