What is a UML Diagram?

Diagrams were drawn in the Unified Modeling Language (UML) to depict complex software systems’ design, architecture, and implementation.

It is a general-purpose, developmental, and modeling language in software engineering that makes system design more visual. It was created by Rational Software in 1994 to standardize the software development process.

Object-oriented analysis and design are related to UML. Class, objects, inheritance, abstract, data encapsulation, and polymorphism are all concepts used in OOP.
