StarUML is an open source project to develop fast, flexible, extensible, featureful, and freely-available UML/MDA platform running on Win32 platform. The goal of the StarUML project is to build a software modeling tool and also platform that is a compelling replacement of commercial UML tools such as Rational Rose, Together and so on.
* UML 2.0 : UML is continuously expanding standard managed by OMG(Object Management Group). Recently, UML 2.0 is released and StarUML support UML 2.0 and will support lastest UML standard.
* MDA (Model Driven Architecture) : MDA is a new technology introduced by OMG. To get advantages of MDA, software modeling tool should support many customization variables. StarUML is designed to support MDA and provides many customization variables like as UML profile, Approach, Model Framework, NX(notation extension), MDA code and document template and so on. They will help you fitting tool into your organizational cultures, processes, and projects.
* Plug-in Architecture : Many users require more and more functionalities to software modeling tools. To meet the requirements, the tool must have well-defined plug-in platform. StarUML provides simple and powerful plug-in architecture so anyone can develop plug-in modules in COM-compatible languages (C++, Delphi, C#, VB, …)
* Usability : Usability is most important issue in software development. StarUML is implemented to provide many user-friend features such as Quick dialog, Keyboard manipulation, Diagram overview, etc.
StarUML is mostly written in Delphi. However, StarUML is multi-lingual project and not tied to specific programming language, so any programming languages can be used to develop StarUML. (for example, C/C++, Java, Visual Basic, Delphi, JScript, VBScript, C#, VB.NET, …)
