UML Weekend Crash Course

ABOUT THE TECHNOLOGY
What it is: UML (Unified Modeling Language) is a graphical modeling language used to specify, visualize, construct, and document applications and software systems, which are implemented with components and object-oriented programming languages, such as Java, C++, and Visual Basic. UML incorporates the object-oriented community's consensus on core modeling concepts and provides a standard way for developers to communicate the details of system design and development. In addition to object-oriented modeling of applications, UML is also used for business-process modeling, data modeling, and XML modeling.
Purpose of modeling: Models for software systems are as important as having a blueprint for a large building, or an outline for a book. Good models enhance communication among project teams and assure architectural soundness. The more complex the software system, the more important it is to have models that accurately describe the system and can be understood by everyone. UML helps provide this via a standard for graphical diagrams. Just like an architect can understand the notations on any blueprint, UML enables software engineers and business managers to understand the design of any software system, even if the original designers have long left the company.
Organization behind it: Object Management Group (OMG) (www.omg.org). (UML Resource Page at OMG Web site is www.omg.org/uml.) The OMG produces and maintains the UML standard, an internationally recognized standard. The OMG is an open membership, not-for-profit consortium that produces and maintains computer industry specifications for interoperable enterprise applications. Its membership roster (about 800) includes just about every large company in the computer industry and hundreds of smaller ones. Most of the companies that shape enterprise and Internet computing are represented on the OMG's Board of Directors.
