Unified Modeling Language (UML)

Unified Modeling Language (UML)

1. The OMG's UML helps you specify, visualize, and document models of software systems, including their structure and design, in a way that meets all of these requirements.

2. You can use it to model non-OO applications as well in, for example, Fortran, VB, or COBOL. UML Profiles (that is, subsets of UML tailored for specific purposes) help you model Transactional, Real-time, and Fault-Tolerant systems in a natural way.

3. A model plays the analogous role in software development that blueprints and other plans (site maps, elevations, physical models) play in the building of a skyscraper.

   • You can model just about any type of application, running on any type and combination of hardware, operating system, programming language, and network, in UML.

4. UML 2.0 defines thirteen types of diagrams, divided into three categories: Six diagram types represent static application structure; three represent general types of behavior; and four represent different aspects of interactions:

   • Structure Diagrams
   • Behavior Diagrams
   • Interaction Diagrams
