Description And Implementation Of A Domain Business Component System

The rapidly changing of enterprise environment bring the possibility of value creation ordestruction. How to reconstruct the enterprise information system has become a very important issue.There are famous EA framework such as TOGAF, Zachman in industry to guid a way to EIresearching. However these architectures only describe the morphology, lacking a specific reference.The way to EI solving is difficulty to advance.Component is a high level of software reuse. It aiming at the reusing of requirements, analysis,design, coding and testing, which inspires EI solution. Conducting CBM and Accumulating businesscomponents upon the component platform can help the enterprise make better use of existing assetsand capabilities to reshape the competitive advantage and ultimately improve their flexibility andefficiency.On the one hand, this paper summarize, sublimate and extract business factors. On the otherhand, we adopt component ideology which insists separation of concern and hierarchical toencapsulate business factors. We describe the component in the way of XML, XML Scheme and BNF.Then we propose a concept of MacroComponent. Finally the framework of business componentarchitecture platform emerge to our mind.In the end, we use the theory of the proposed business component, defining Macro Componentupon the Justep x5platform. Consequently we imposed component-based analysis andcomponent-based development on the xx Research Institution office system, verifying the feasibilityand rationality of the business component description system,solving the B-T estrangementeffectively,improving the development efficiency.
