Usage of UML models at design an order system

The Unified Modeling Language (UML) is the most-used graphic specification. It shows not only application structure, behavior, and architecture, but also business process and data structure. UML also provides unification of every step of development and integration from business modeling, through architectural and application modeling, to development, deployment, maintenance, and evolution. The target of this thesis is the description of UML and its usage in software development process. UML helps to inscribe the process, the software application and make the communication in development group easier. The big advantage of UML is the opportunity of using computer-aided software engineering for generating source code from UML models. It saves a lot of work with manual typing code, making documentation and deploying the application
