What is UML?
A Unified Modeling Language diagram combines the Booch, OMT, and OOSE methods to simplify, describe, and explain complex business processes. There are nine types of UML diagrams: class (package), object, use case, sequence, collaboration, state chart, activity, component, and deployment. For more information on these, please visit our "How to Create UML Diagrams" section. Each are constructed fairly similarly with a few minor differences.
UML diagrams are put to use any time a system or process needs to be put in a more comprehensible form. UML diagrams are widespread and used by numerous system and software companies. UML is specifically designed for software engineers and can be easily translated into other programming languages.
