The Unified Modeling Language (UML) is a standard general-purpose modeling notation for object-oriented analysis and design of systems.
System Architect currently supports the following versions of UML, that are separate and distinct:
▪UML 2.0 Lite which is based on the UML 2 metamodel.
▪UML 2.5 which provides a detailed implementation of the UML 2.5 specification. For details, see UML 2.5.
It is strongly suggested you choose to use one or the other – not both. They are distinctly different metamodel implementations; turning both on would only serve to confuse you.
Although UML does not dictate a standard process or method for developing an object-oriented system (see Developing systems with UML), it does prescribe a standard set of diagrams and notations, which enables the user to model certain aspects of a system.
Summary of UML diagrams
UML specifies several types of diagrams to build a system. These diagrams are classified as follows:
