UML (Unified Modeling Language) is an object-oriented analysis and design language. It can be defined as a general-purpose language that uses a graphical designation, which can create an abstract model that can be used in a system (UML model). This abstract model can then be used in a system. This system is called the UML model. The Object Management group is responsible for defining UML, and they do this via the UML met model. XMI can be used to serialize the UML model. UML is primarily used to construct software intensive systems.

UML supports twelve diagramming methods including structural (class, object, component, deployment), behavioral (case, sequence, activity, collaboration, state chart) and model management (incorporating packages, subsystems and models). If you are interested in learning computer languages or particularly UML, then you can go for the UML educational tutorials. Within the course of the tutorial, a programmer can learn the basics of UML diagramming structures. The tutorials offer information that includes UML theory and practical usage. The thorough tutorial provides the learners with lessons, questions and exercises to further practice development of UML. Or you can also go for good books on this subject.
