New IEEE Standard - Active.IDEF1X97 consists of two conceptual modeling languages. The key-style language supportsdata/information modeling and is downward compatible with the US governmenta??s 1993 standard, FIPSPUB 184. The identity-style language is based on the object model with declarative rules and constraints.IDEF1X97 identity style includes constructs for the distinct but related components of object abstraction: interface, requests, and realization; utilizes graphics to state the interface; and defines a declarative,directly executable Rule and Constraint Language for requests and realizations. IDEF1X97 conceptualmodeling supports implementation by relational databases, extended relational databases, objectdatabases, and object programming languages. IDEF1X97 is formally defined in terms of first order logic. A procedure is given whereby any valid IDEF1X97 model can be transformed into an equivalent theory in first order logic. That procedure is then applied to a meta model of IDEF1X97 to define the valid set of IDEF1X97 models.
