Stands for Unified Modeling Language. UML is a standard notation and modeling technique for analyzing real-world objects, developing systems, designing software modules in object-oriented approach. UML has been fostered and now is accepted as a standard by the group for creating standard architecture for object technology, OMG (Object Management Group).

UML is an industry-standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems standardized by the Object Management Group. UML simplifies the complex process of software design by using “blueprints” for software construction. Widespread adoption of UML is one of the forces contributing to developer demand for tools that can represent more intentional problem-related information.
