Research Of Data Integration Method Based On Information Grid

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.
