The UML was invented primarily to address the challenges faced in the design and architecture of complex systems. The basic objectives or goals behind UML modeling are:

·         Define an easy to use and visual modeling language for modeling a system's structure

·         Provide extensibility

·         Be language and platform independent so that it can be used for modeling a system irrespective of the language and platform in which the system is designed and implemented

·         Incorporate the best possible practices at par with the industry standards

·         Provide support for Object Orientation, design and apply frameworks and patterns
