Summary of the OMT methodology
The OMT methodology was designed to present different points of view when describing a system. For this purpose, the following methods are used:
Object modeling
Dynamic modeling
Functional modeling
These three views are orthogonal to each other, but cannot be viewed as being entirely independent of one another.
Object modeling represents the static, structural, and data-related aspects of a system. The structure of objects, their relationships to other objects, and their attributes are illustrated.
Dynamic modeling illustrates the aspects of a system that relate to time, behavior, and control. The sequence of operations is described by depicting the sequence of events.
Functional modeling shows the transitional and functional aspects of a system. The transformation of values is described here.
These models contain references to each other. For example, the object model describes data structures that are used in the dynamic model and functional model. The processes in the functional model correspond to the operations in the object model. A statechart diagram of the dynamic model describes - in whole or in part - the behavior of an object of a class in the object model.
