We hope it will be help to Academic person, Student, Research, and those who are interested in software engineering field.Since UML is a Unified Modeling Language, it is used to create meaningful, object-oriented models for a software application. In this we present paper summarized study on open source technology, UML, StarUML. StarUML is excellent in customizability to the user’s environment and has a high extensibility in its functionality. StarUML is an open source tool to develop fast, flexible, extensible, featureful, and freely-available UML/MDA platform running on Win32 platform. Nearer to 200 Commercial and open source tools which provide UML modeling capabilities available in market. In the last decade, the Unified Modeling Language (UML) has become a de-facto standard as modeling language in software engineering. The Unified Modeling Language (UML) is the most widely used design notation for software at this time, unifying a number of popular approaches to specifying structure and behavior. One of the most popular languages that are used to represent software design is the UML.

Wide range of modeling tools that make it relatively easy to lay out the functionality and use cases for a new project. Abstract Poor planning is one of the top reasons why software projects are delivered late, over budget, or not at all, so it’s important to get organized before start coding.
