Part 1: What is UML Communication Diagram?

Unified Modelling Language (UML) is a type of language used to illustrate the inner workings of a system, which include its actors, actions, roles, and classes. Originally used in the fields of software and engineering, UML has now made its way into business, and is a popular method of documenting business processes.

UML primarily uses diagrams to represent systems. These diagrams can be broken down into two types: behavioural UML diagrams, and structural UML diagrams.

UML is an extremely versatile and widely-recognised language. It is the standard language used by many developers, as well as an increasing number of business professionals. Its flexibility means that it can be applied to a number of IT or business-related situations, so that you can make it applicable to the system or technology you are using.
