【摘要】 为提高软件复用程度、系统开发效率和可维护性,提出了基于平台化、构件化的系统开发思想。应用结构化、模块化和面向对象方法,在J2EE支撑平台的基础上,研究了软件构件定义、属性、表现和模型,构件分类与管理技术。阐述了基于平台和构件的开发过程。在多个项目中应用表明,系统的开发效率被提高了20%左右,软件复用性显著提高,可维护性明显增强。更多还原

【Abstract】 To improve development effect,maintenance and reused ratio of software system,an idea of development based on software platform and component is presented.These methods of object-oriented,structured and modular are applied.Some models,define,properties and present of component,and component classified,component management have been studied base J2EE support platform.A process model and development method component base of software development and platform are described.The result of some applications has illustrated that reused ration,maintenance,is obvious improved,and about 20 percent effect of application development is improved.更多还原
