一种具有性能约束的软构件集成模型

An integration model of performance constraint software component

在具有性能约束构件模型的基础上,提出了一个由构件层和服务层组成的具有性能约束的软构件集成模型.通过服务层提供的构件性能属性识别器、构件容器、集成工具、适配器等设施的协同工作,把分布于不同网络的、基于性能约束构件模型开发的构件进行集成,实现了具有性能约束构件的集成.由于对于不具有性能约束构件的集成,该模型的构件性能属性识别器不用启动运行环境,从而节省了系统开销.该模型既考虑了具有性能约束构件的集成,又可实现一般构件的集成,有助于软件复用.

On the basis of performance constraint soItware component, a performance component integration model was proposed. The integration model included component and service layers. Using the infrastructures provided by the service layer, such as, component identifier, container, integration tool, adapter, this model can integrate the component based on performance constraint component model（PCCM） distributed on different network. It can implement component integrating with performance constraints in this way. With regard to the integration of component with no performance constraint, the identifier of the model don＇t activate the initialization environment, to save system expenses. This model concerns both sides of the component with performance constraints and with no performance constraints, being helpful to software reuse.
