1. What is a UML Diagram
UML is a set of diagrams that can be used to visualize a software program. Grady Booch, James Rumbaugh, Ivar Jacobson, and the Rational Software Corporation developed the notation to be used for object-oriented design, but it has subsequently been expanded to cover a broader range of software engineering projects. The Object Management Group (OMG) now recognizes UML as the standard for modeling software development.
