UML

Unified Modeling Language (UML) is a language used for Visual Modeling of software-intensive systems. UML is a standard language used to describe, visualize, and document products of object-oriented development systems. The Unified Modeling Language (UML) is a non-patented third-generation modeling and Protocol language. UML is an open method for describing, visualizing, constructing, and writing products of an object-oriented software-intensive system in the development stage. UML presents a series of best engineering practices that have been validated for effective modeling of large-scale, complex systems, especially at the software architecture level. UML can run through every stage of the software development cycle. Adopted by OMG as the industry standard. UML is most suitable for data modeling, business modeling, object modeling, and component modeling. As a model language, UML enables developers to focus on building product models and structures, rather than selecting program languages and Algorithms for implementation. After the model is created, the model can be converted to the specified program language code by the UML tool. IBM's Rational Rose and Ms's Visio are both UML tools.
