目前针对软件即服务SaaS(Software asa Service)的可配置策略还没有完全形成成熟的理论.借鉴已有技术,提出和描述基于组件组装定制服务的一种配置模型.该配置模型允许用户对服务进行建模,根据自己特定的业务流程,基于相同的服务组件,通过定义不同的数据关联和约束规则实现服务流程定制.最后通过两个业务需求不同的服务的配置实例,证明所描述方法的灵活性和可行性.%Now for SaaS,or Software as a Service, strategy that can be configured has not yet fully formed a mature theory. This article draws on existing technology, proposed and described component-based assembly configuration model. The configuration model allows the user to model the service, according to their specific business work flow, based on the same service components, by defining different data association and constraint rules to achieve configurable flow model. Finally,examples of two services with different business needs, show the flexibility and feasibility of the methods which is described in this article.
