基于网格技术的电子政务体系结构

E-government architecture based on grid

电子政务中当前的信息交换技术无法实现完全意义上的信息互通,不同系统之间存在概念的差异、安全的鸿沟和一致的工作流程等问题。结合电子政务的需求和网格技术,提出了一个基于网格技术的电子政务体系结构。在此基础上,进一步就电子政务中的安全策略、本体和工作流等几个方面进行了研究,设计了适合于电子政务的模型。

The main issue of the E-government is how to integrate each government agency＇s resources to form cross-agency services, that is, the concept lack of consistency in deference systems, there are a great gulf fixed of trust in cross-agency services and haven＇t run-through workflow. Grid technique provides an ideal way to solve this problem. Architecture of E-government based on grid techniques is presented, and then the workflow, ontology and security policies framework are discussed in detail.
