The emergence of Unified Modelling Language (UML) as a standard for modelling systems has encouraged the use of automated software tools that facilitate the development process from analysis through coding. In our approach UML class diagram is used to generate XML schema and generated xml schema is used for code generation. In our approach UML class diagram is used to generate XML schema and generated xml schema is used for code generation. We have implemented a system for XML Schema generation using .net platform. .net is helpful in fastly generating the tool. A tool named JIBX is used for code generation which is developed by IBM and also a open source tool.
