Designing business process is very complex as it involves activities, resources, products and tools. Adopting the concept of Domain Specific Modeling helps creating and using business processes, packaged as services and enable reusability, loose coupling, higher abstraction, agility, and interoperability. Domain specific modeling can be used to design the business processes as it increases the business centric value as well the productivity and quality. In this paper, GME tool is used for creating DSM of business process and also discussed how business processes are captured and defined at domain level. Also the Design of business process and entity meta-model 's and its interpretation to generate the Input model is shown in detail. GReAT Tool is used for applying Configuration and Transformation rules on the imported models. Finally full code Generation is shown. © 2008 IEEE.
