The accepted open standard that is used in software engineering and system design, when modeling object-oriented systems and business processes is known as Unified Modeling Language (UML). UML was created for definition, visualization, design and documentation software systems. It isn't a programming language, but on the base of UML model can be generated code. UML uses generic set of graphic notations for creation an abstract model of the system called UML-model. The UML notation lets visually represent requirements, subsystems, structural and behavioral patterns, logical and physical elements, etc.
UML defines 13 types of diagrams: Class (Package), Use Case, Sequence, Object, Collaboration, Component, Timing, Interaction Overview, State Machine, Composite Structure, Activity, and Deployment. All these types of UML Diagrams can be fast and easy created with powerful ConceptDraw DIAGRAM software extended with special Rapid UML solution from Software Development area of ConceptDraw Solution Park.
