面向服务的企业门户架构及其实现的研究

为克服传统企业门户架构紧密耦合且无法满足需求多变的缺陷，提出了面向服务的企业门户架构（ServiceOriented Architecture for Enterprise Portal，SOA4EP），为企业门户的设计与实现提供一个完善通用、协同高效和松耦合的软件架构策略；给出了门户组件整合和Web服务集成的实现模式，并探讨了服务粒度和质量控制方法。最后通过应用实例说明该研究结果可为企业门户构建过程的标准化提供重要的参考依据。

Research on Service Oriented Architecture for Enterprise Portal and Its Implementation

To overcome the limitation that traditional architectures of EP were compact and couldn't satisfy those variable requirements,Service-Oriented Architecture for Enterprise Portal(SOA4EP) is presented.As an adaptive,cooperative,efficient and loose software architecture policy,SOA4EP could be shared during the design and implementation of EP.The business logic functions are divided according to a distribute integration framework with Web services higher than object layer.It is used to integrate dynamically various service components based on different technologies.An implementation mode of integration with portlets and Web services is provided.And consequently a method is discussed to control granularity and quality of service.The research result has great significance to the standardization of configuration process.
