摘　　要：企业信息系统开发面临诸多问题,软件产业希望借助于“构件”技术提高软件生产率,但其实践并未达到预期效果:构件设计的方法学还不完善,缺乏对实际应用的明确指导。该文从应用体系结构入手,根据沈飞项目实践经验,总结出两类构件(过程构件、实体构件)的设计方法。分析COM+构件实现机制的原理和特点,从中总结出提高应用系统效率的构件实现方案。该文的研究成果已应用于沈飞物资供应系统,具有较好的实际意义。The Development of enterprise information system is faced with many problems.Software industry hopes to increase software productivity by'component 'technology,but in practice it doesn't reach the expectation:the methodology of component design is not perfect,lack of concrete instruction to practical application.In this paper,according to the application architecture and the practical experience of ShenFei Project,the design methodology of two types of components(process component ,entity component )is given.The principles and characteristics of COM+Component imple-mentation are discussed,and a component implementation schema for improving the system efficiency is summarized.The research production of this paper has been used in shenfei material procurement system,and gets preferable result.
