【摘要】 随着我国经济建设和科学研究的发展,各行业信息化步伐加快。在行业内部的信息化建设过程中,各个部门根据各自内部的需求和应用开发了基于不同数据源的应用系统。但是,由于各行业积累的信息越来越多,数据量大、处理复杂、难以共享等问题已经对信息系统的研究和应用提出了挑战。传统的信息系统体系结构、处理方法和技术已无法满足信息多层次、多方式与多样化应用的需求,需要新的技术和方法来管理、访问、整合、分析各行业海量分布的各种信息资源。在这种情况下,如何将这些应用系统的数据进行集成,实现行业内部的数据集成和共享,满足各应用系统之间在业务与安全范围内实现互联互通与互操作的需要,以适应在Internet环境下对网络业务的交换、共享、协同和控制的需求,对于整个行业的发展具有非常重要的意义。 本文的主要内容是基于信息网格的数据集成方法的研究。采用信息网格将最大限度地实现信息资源共享、重用和互操作,因此,论文从数据集成的任务和目前所面临的关键问题出发,提出了一种基于信息网格的数据集成解决方案。论文的主要工作包括以下三个方面: 首先,在总结分析国内外现有的信息网格研究成果的基础之上,选用了一种开放的信息网格体系结构OIGA(Open Information Grid Architecture)的5层结构模型来构建数据集成平台框架。 其次,为了更好地满足Internet环境下对于信息的多样化访问和集成的需求,屏蔽网格底层中复杂的资源管理机制,论文借鉴了Web Services技术,通过建立相应的信息服务管理中心,从而实现信息网格面向用户交互的共享、管理、集成和应用。 最后,论文以民航空管信息整合的具体需求为实例,采用了基于信息网格的数据集成平台框架构建民航空管信息整合系统,并在此基础上讨论了基于信息网格的数据集成方法的优缺点。更多还原

【Abstract】 The informationalization in all industries has speeded up along with the development of our country’s economy and scientific research. Each department has developed their own application systems based on different data resources according to respective internal demand and application in the construction of the informationalization. But the massive data, complex processes, hardness to share and so on have challenged the research and application of the information system as a result of the accumulation of the information. The structure, process method and technology of traditional information system are unable to satisfy the demand of the multi-levels, multi-ways and the diverse application. And it needs the new technology and method to manage, visit, conformity and analyse the magnanimous information resources distributed in all industries. Under this condition, it’s great significant to the development of the whole industry that how to integrate these application systems, realize the data integration and share in industry interior, and satisfy the demand of the interconnection and interoperation in operation and security scope between each application system in order to fit the demand of the net service exchange, share, coordination and control in the Internet environment.The main content of this article is the research of data integration method based on the information grid. The adopting the information grid will be helpful to realize the share, reuse and interoperation in information resources. Therefore, the paper proposes a data integration solution based on the information grid. The main work of the paper includes the following three aspects:In the first place , based on the summarization and analysis of the existing results of domestic and foreign research, the paper adopt five-structure model of OIGA(Open Information Grid Architecture) to construct the framework of platform for data integration.In the second place, the paper use the technology of Web Services for reference in order to better satisfy the multiple access to information on Internet and the needs of integration through setting up corresponding information service management centers.Using this method, it can provide the function of share, management, integration and application from information grid to user interaction.At last, taking the particular requirements of Civil aviation air traffic control’s information integration for example, the paper introduce the framework of data integration platform based on information grid to construct the information integration system of Civil aviation air traffic control. And on this basis, discuss the advantages and disadvantages of methods of data integration based on information grid.更多还原
