Summary

The Unified Modeling Language (UML) gives people a shared visual way to describe systems. Like a blueprint for a building, a UML model can communicate a system’s structure and behavior before or during implementation.

UML is a general-purpose, object-oriented visual modeling language. It defines notation and meaning for diagrams that represent different aspects of a system, including its structure, behavior, and interactions. UML 2 defines 14 diagram types.
