Grammar-oriented Object design (GOOD) uses a business domain-specific language to model the flow an constraints on a set of collaborating enterprise components (EC). Maintenance of these components and their flow composition is a major issue. We present a software tool called the, Business Compiler (BC) that facilitates the definition, debugging and execution of business flow languages in order to help animate and execute the collaboration of components reflecting the business process steps defined by a business modeler. Architects enhance the grammar with component services that serve as actions in,the grammar. The combination of flow definition by modelers and component services by software architects provides a powerful collaborative environment for enabling the incremental creation of a highly re-configurable-architectural style. BC consists Of an application framework that supports component-based development and includes a GUI debugger front end This helps modelers by providing dynamic documentation an can be used by architects to create and execute a formal specification of business flow to facilitate maintainability through a highly adaptive and re-configurable architectural style.
