摘要
针对应用系统需灵活地动态演化以适应动态开放的底层因特网环境和灵活多变的用户需求的需要,提出一种面向服务对象的动态演化机制。该机制把软件设计阶段易变的部分建模成服务对象,并借鉴面向服务的服务注册和查询机制,利用服务对象注册表解耦对象的引用实现软件演化。详细介绍了该演化机制及其演化过程,并与相关的代表性研究工作进行对比,通过实验表明该机制比面向服务具有更好的性能。
A service-object-oriented dynamic evolution technology was proposed to facilitate application software＇s dynamic adaptation requirement for the evolving Internet environment and variable user requirements.Under this mechanism,the variable parts were modeled into service-object,then the service registration and lookup mechanism referring to service-oriented computing were utilized to decouple the object reference for evolution.The evolution mechanism and evolution process were described in detail.Some contrasts were made among the representative research work.The experimental results show that the mechanism has better performance.
