Translation of behavioral models to source code

It is a wonderful idea to directly execute the system designs. In this paper we are introducing a method to convert the behavioral models to the implem entation code. UML is used for modeling and Java is used a s the target language. This paper describes how a system design depicted using activity, sequence and statemachine diagrams can be converted to its implementation code. Activity diagram helps to make the outline of the source program, and the sequence and state machine diagrams contribute to the expansion of the source code. We are using an MDA approach where the system design is do ne in Platform Independent Model (PIM), then converted to Platform Specific Model (PSM) and finally to implementation code. One tool is imple mented based on ou r method and it is evalu ated against some other existing tools.
