SOFTWARE REUSE AND INDUSTRIALIZATION

Building applications by composing pre-developed §components has promise for reuse and software §engineering industrialization. Model-Driven §approaches not only elevate the abstraction of the §development, but also leverage the integration §tools for various supporting functionality such as §analysis, transformation, simulation, optimization, §and monitoring. A transformation framework, called §Regular Expression Language is used for §integration of service components. The integration §requirements are depicted as a graphical process §model and then are transformed into Business Process §Execution Language (BPEL). We solved the theoretical §difficulty to generate non-exponential BPEL when the §process model presents irreducibility. We also §present a Model-driven Domain-specific Integration §Language to integrate the source or binary §code of the software components. Two-Level Grammar++ §is used to specify feature models so that §the integration requirements can be validated §against domain feature model specification. §Glue/wrapper code generation is discussed for §integrating heterogeneous components.
