What is UML Diagram- Unified Modelling Language?

Answer: The UML (Unified Modelling Language) Diagram is a standardized modelling language of describing, designing and documenting a software system in object-oriented software engineering. There are many UML diagrams like Class diagram, Sequence diagram & Activity diagram etc. that are used to model software system, behaviour and business processes of the system.

Major goal of UML diagrams is to communicate an idea of a system amongst people like Technical Architect, Clients and developers.

  • It is independent of any specific Platform, Language & Technology.
