In this step-by-step tutorial, we'll show you how to make a UML sequence diagram using Lucidchart. However, this definition is too generic to describe the purpose, as other four diagrams (activity, sequence, collaboration, and Statechart) also have the same purpose. Class Diagram defines the types of objects in the system and the different types of relationships that exist among them. The Unified Modeling Language (UML) can help you model systems in various ways. Unlike other charts, UML activity diagram can be used under different circumstances. It also renamed statechart diagrams to state machine diagrams, also known as state diagrams. The notation has evolved from the work of Grady Booch, James Rumbaugh, Ivar Jacobson, and the Rational Software Corporation to be used for object-oriented design, but it has since been extended to cover a wider variety of software engineering projects. There are many different types of UML diagrams and each has a slightly different symbol set.
