Editing Unified Modeling Language (section)

=== Before UML 1.0 ===
UML has evolved since the second half of the 1990s and has its roots in the [[object-oriented programming]] methods developed in the late 1980s and early 1990s. The timeline (see image) shows the highlights of the history of object-oriented modeling methods and notation.

It is originally based on the notations of the [[Booch method]], the [[object-modeling technique]] (OMT), and [[object-oriented software engineering]] (OOSE), which it has integrated into a single language.<ref name=":0" />

[[Rational Software Corporation]] hired [[James Rumbaugh]] from [[General Electric]] in 1994 and after that, the company became the source for two of the most popular object-oriented modeling approaches of the day:<ref>Andreas Zendler (1997) ''Advanced Concepts, Life Cycle Models and Tools for Objeckt-Oriented Software Development''. p.&nbsp;122</ref> Rumbaugh's [[object-modeling technique]] (OMT) and [[Grady Booch]]'s method. They were soon assisted in their efforts by [[Ivar Jacobson]], the creator of the [[object-oriented software engineering]] (OOSE) method, who joined them at Rational in 1995.<ref name=":1">{{cite book
