Visual Paradigm for the Unified Modeling Language (VP-UML) is a full-featured UML tool designed for building large scale software systems reliably through the use of the object-oriented approach. VP-UML supports the latest standards of Java and UML notations. In addition, VP-UML is integrated with all leading IDEs to support the implementation of software development. The transitions from analysis to design and then to implementation are seamlessly integrated within the CASE tool, thus significantly reducing efforts in all stages of the software development life-cycle.
