The object-modeling technique (OMT) is an object modeling language for software modeling and designing. It was developed circa 1991 by Rumbaugh, Blaha, Premerlani, Eddy and Lorensen as a method to develop object-oriented systems, and to support object-oriented programming.
OMT is a predecessor of the Unified Modeling Language (UML). Many OMT modeling elements are common to UML.
