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.
