INTEGRATION OF HETEROGENEOUS DISTRIBUTED COMPONENTS USING WORKFLOW INFORMATION

摘要

Component-based software engineering (CBSE) is becoming widely used for software development. CBSE is based on integrating previously developed pieces of software called components. Components may not be just small-grained modules such as classes in object orientation, but may also be large-grained modules (such as EJB, CORBA and Web services). There are, however, issues that exist which make the actual development process non-trivial. This paper considers two such issues: (1) heterogeneity of components and (2) expressing the design of how they can be connected. We have developed a prototype tool that solves these issues by automatically generating adapters for integrating heterogeneous components, and that uses UML's activity diagram to specify the workflow which expresses the design of the software to be developed.
