【摘要】 当前,我国各级政府行政方式开始逐渐打破原有的条块壁垒,向“一站式”方向发展,越来越多的政府职能需要跨地域、跨部门联合完成。这就要求我国政务信息化建设必须充分利用己有的网络基础、业务系统和信息资源,加强整合,促进互联互通、信息共享,使有限的资源发挥最大效益。这一发展趋势充分表明,目前我国政务信息化建设的重点己经由业务信息化逐渐转向信息资源的整合共享和开发利用。于是,数据整合已成为我国政务信息化基础设施建设的重点。政府门户网站是提供“一站式”公共服务和整合发布政务信息的窗口。针对这一需求,航天四创及时推出了内容管理产品ASOP-CMP,它很好的解决了对非结构化数据的统一管理问题,数据共享的矛盾并不突出。因此,本文侧重于如何对结构化数据进行整合,提出了一个基于CWM&XMI的标准化的数据整合模型和实现方案。论文对国内外数据整合技术的发展现状以及发展趋势进行了深入地调查与研究,了解了现有数据整合产品的不足,总结出一个基于CWM&XMI的数据整合模型。DCP模型采用集中式资源管理模式,数据中心对整个数据整合过程进行集中控制和管理,适配器作为业务系统的代理在元数据信息的控制下与数据中心通过Web Service调用完成数据的交换和共享。ASOP-DCP是一个基于Java技术的对该模型的实现原型,文中首先给出了系统的实现目标并对功能模块进行划分,接着对其中一些关键问题进行了细致的设计。最后,将ASOP-DCP作为ASOP-CMP功能的重要扩展,成功应用在了实际项目之中,验证了模型的可行性与实用性。更多还原

【Abstract】 At present, administrative mode of governments at all levels begins to break the barriers gradually. More and more government’s jobs need to be completed in a way of inter-departmental joint. All requires that China’s government information construction must make full use of own network infrastructure, business systems and information resources, strengthen integration, promote interoperability and share information so that the limited resources to achieve maximum efficiency. This trend shows that China’s government information construction has began to convert from building business systems to integrating information resources. Therefore, data conformity is becoming emphases in the foundation establishment of China’s government information construction. The government’s portal site should be a window which to provide "one-station" services and release government affair information. In response to this demand, Aerostrong company developed timely a content management product (ASOP-CMP). It is a good solution for the unstructured data management, so conflicts of data sharing were not prominent. Therefore, the dissertation focuses on how to integrate structure data and present a model based on CWM&XMIThe dissertation first carried on thoroughly investigation and research to the present status of data conformity technology in domestic and foreign. Understanding the inadequacies of the existing data integration product, we conclude a data conformity modal based on CWM&XMI. DCP model introduces a kind of mode named centralized resource management mode. Data center carried out centralized control and management in the process of data conformity. As a application’s agent, the adapter exchanges and shares data with data center through Web Service and Meta-data. ASOP-DCP is a Java-based prototype of this model. This dissertation first advanced a goal of the realization and divide system functions into different modules. Then some of the key issues is designed in detail. Finally, being a important extension to ASOP-CMP, ASOP-DCP has been applied in practical project and it proved the feasibility and the usability.更多还原
