Enhancing UML activity diagrams using OCL

Business process automation is very much important for the customer satisfaction and for good productivity. UML Activity diagram is a behavioral diagram which is suitable to model business process. The activity diagram can be enhanced using Object Constraint Language (OCL). This elaboration will help us to include more implementation specific details in the activity diagram. In this paper we present different possibilities to include OCL in the activity diagram and their metamodels. The paper proposes an algorithm to convert the OCL statements to a target code. The OCL enhanced activity diagram can be converted to any target language like Java, C++ etc. In this paper we are converting the system design, represented in activity diagram, to Java code. We also present a prototype of the code generator named ActivityOCLKode and we evaluate the prototype with parameters like complexity, percentage of code generated.
