Object–role modeling

Early versions of object role modeling were developed in Europe in the mid-1970s (for example, binary relationship modeling and Natural Language Information Analysis Method (NIAM)). The version discussed here is based on the Terry Halpin formalization of the method, and incorporates extensions and refinements arising from research conducted in Australia and the United States. The associated language FORML (Formal Object-Role Modeling Language) is supported in Microsoft® Visio® for Enterprise Architects (VEA), part of Visual Studio® .NET Enterprise Architect.
