Modeling is an essential phase and the most important activity which is done while building complex systems and structures. It produces a system artifact called a system model. System model is an abstraction or approximate representation of the real item to be built. Modeling allows visualizing entire systems, assess different options, and communicate designs before the developer take on the risks associated with actually building something. In the field of the software engineering, modeling process should cover all the principles, concepts and functionalities of the software system to be built. The complexity of software systems and their parallel, distributed and heterogeneous nature raises many challenges when trying to ensure their correctness. The unified modeling language (UML) is the de facto standard for modeling, designing and architecting software systems. It tends to be the most powerful and commonly used software modeling and visualizing tool in the software engineering industry with a large variety of diagram types which offer a large degree of freedom. UML tools are used in order to describe the aspects of the software system
