What is OMT?
James Rumbaugh's Object Modeling Technique (OMT) is one of the precursors to the Unified Modeling Language (UML). There are three main diagrams in OMT: object, dynamic, and functional.
Object View Diagrams
The OMT object model illustrates the static relationship among classes and objects in a system. This diagram is similar to the UML object and class diagrams.

Classes
You can illustrate a class in SmartDraw using a rectangle divided into three compartments: name, attributes, and operations. This notation is the same as the class symbol used by UML.

Objects
Draw an object using a rectangle with rounded corners. Attributes must have values assigned to them.
