The term class is used in object-oriented programming to define a data structure consisting of properties and functions (also called methods).
Object diagrams are a set of objects and their relationship is just like class diagrams. If the automobile gets destroyed, so will the tires.

The re-, sultant formal models of the approach will be verified, and validated using Z/Eves toolset. The elements are like components which can be associated in different ways to make a complete UML picture, which is known as diagram. This is because, unfortunately, much of the UML struc-, tures are based on graphical notations having informal or, as mentioned above. Typically, a package is specific to a programming language or framework.
An association relationship is when one component or class works with another component or class.

The class diagram does not describe a particular instance of an InstructionalVideo, Instructor, or LanguageProficiency. This integration of formal notations and UML, diagrams will result an approach for complete, consistent, and correct modeling of a system. Property ori-, ented methods are used to describe software in terms of, properties, constraints and invariants whereas model ori-, ented methods are used to construct a model of a system, [35]. can be simple, concurrent, non-concurrent, initial or final. by Finally conclusion and future work are discussed in Sec-, Although there exits a lot of work [6-10] on integration of, UML diagrams with formal approaches. search Group at the Department of Computer Science.

Dynamic diagrams in UML describe the operations, actions, and changes that occur in a system over time. Similarly, it is, also possible that when a transition is fired from one state, s1 to another state s2 there exists an inverse transition, which can be fired from s2 to s1 that is there exists a, collection of states over which the symmetric relation is, defined. complement operations over the sets are not defined. The schema also defines a way in, which the stat e of a system can be desc ribed and hence can, be used for modeling the dynamics of a system as well.
