Rational established the UML Partners consortium with several organizations willing to dedicate resources to work toward a strong UML 1.0 definition.During 1996, the first Request for Proposal (RFP) issued by the Object Management Group (OMG) provided the catalyst for these organizations to join forces around producing a joint RFP response.UML also includes new concepts that were not present in other major methods at the time, such as extension mechanisms and a constraint language. UML has also been influenced by other object-oriented notations: The team of Rumbaugh, Booch and Jacobson are affectionately known as the "Three Amigos" The aim of the partnership was to merge their ideas into a single, unified method (the working title for the method was indeed the "Unified Method").īy 1995, the creator of OOSE, Ivar Jacobson, had also joined Rational, and his ideas (particularly the concept of "Use Cases") were fed into the new Unified Method - now called the Unified Modelling Language1.

In 1994, Jim Rumbaugh, the creator of OMT, stunned the software world when he left General Electric and joined Grady Booch at Rational Corp. Use Cases are a powerful technique for understanding the behaviour of an entire system (an area where OO has traditionally been weak). OOSE (Object-Oriented Software Engineering ) - featured a model known as Use Cases.Although the Booch method was strong, the notation was less well received (lots of cloud shapes dominated his models - not very tidy) Grady Booch had worked extensively with the Ada language, and had been a major player in the development of Object Oriented techniques for the language. Booch - was excellent for design and implementation.Object Modeling Technique OMT - was best for analysis and data-intensive information systems.UML is a notation that resulted from the unification of OMT from Hence, it provides constructs for a broad range of systems and activities (e.g., distributed systems, analysis, system design and deployment). UML has been designed for a broad range of applications. The goal of UML is to provide a standard notation that can be used by all object-oriented methods and to select and integrate the best elements of precursor notations.
