What is a UML Diagram?

A UML diagram is the graphical representation of a system that is unified or simplified into several use-case scenarios with the actors performing each of them, the relationship between the actors and the tasks, the sequence through which the events/tasks are performed, and more.

When the entire system or work process is represented graphically through a UML diagram, it becomes easier to understand the whole process, the flow, classifications of the events and how one event is related to the other, the actors that are responsible in performing the tasks and their roles for each of them. That is why the current industries, mainly in the software industries UML diagrams, are vastly used to understand the entire software development life cycle (SDLC model). Before planning to launch a new software into the market, the management team along with the software developers, test engineers, and the marketing team analyze several case studies with the help of UML diagrams and decide upon when and how to launch the product.
