【摘要】 本文描述了一个基于面向对象技术的积件系统的设计思想及其工作原理 ,给出了该系统写作组合平台的设计和系统的课件运行的动态模型。该系统将积件对象化 ,面向对象积件库由积件对象组成 ,外部与积件对象、积件对象与积件对象之间只能通过消息发生联系。积件对象通过接受消息驱动相应的教学服务。这样的系统设计可增加积件的独立性与可积性 ,实现课件的动态重组。更多还原

【Abstract】 This paper describes the design and working principle of integrableware system based on object-oriented technology,gives the design of the system authoring assembling plotform and the dynamic mode of courseware performance produced by the system.The integrableware are modelized into object,the integrableware-object can communicates with others or external by news.Accepted news the integrableware-object drives relevant teaching service.The design of the system can increase the independence and integrablity of integrableware,and implicate dynamic re-combination of courseware.更多还原
