UML consists of an integrated set of diagrams, developed to help both System Developers and Software Developers with specifying, visualising, constructing, and documenting the artefacts of software systems, as well as for business modeling and other non-software systems.
The UML is a very important part of developing object-oriented software and the software development process and has proven successful in the modeling of large and complex systems.
The UML uses mostly graphical notations to express the design of software projects, and using the language helps project teams communicate, explore potential designs, and validate the architectural design of the software.
Other IT professionals that utilise UML may include Business Analysts.
