Unified Modeling Language

Unified Modeling Language (UML) is a non-proprietary, third generation modeling and specification language. The use of UML is not only for software modeling. It can also be used for modeling hardware (engineering systems) and is used for business process modeling and organizational structure modeling. The UML is an open method used to specify, visualize, construct and document the artifacts of an object-oriented software-intensive system under development. The UML represents a compilation of best engineering practices which have proven to be successful in modeling large, complex systems, especially at the architectural level.

For large enterprise applications ones that run core business applications and must be running to keep a company going has to be more than just various code modules. In order for there to be a clear structured architecture there must be a way to enable scalability, security and have a beefy execution that programmers can quickly find and fix bugs that show up after the original programmers have moved to other projects. The benefits of structure (and of modeling and design) compound as application size grows large. Another benefit
