Research And Application Of Information Issuing Based Grid Technology

Each Government has a pattern of managing enterprises in it's area, while the implementation of Electronic Government bring forward an aspect that the Government's computer system and enterprise's computer system exists at concurrence. When the government wAnts to publish information about each enterprise ,it need to draw out messages from each erterprise's computer system, which has its own standard on development platform, operating system and database or other aspects. These alone Systems arose a phenomenon of information island, which made Information sharing and synchronization between different systems difficulty. The aim of the this paper is to research cooperation of muti-system in Electronic Government base on Grid Technology, which will resolve the problem of information sharing and synchronization .In this paper ,the author researched several traditional information publishing pattern, after analyzed merits and defects of each information publishing pattern, author puts forward a new information publishing pattern based old pattern ,which is information publishing technology based on Grid technology.Firstly , this paper studied the architecture of Grid and used Grid service implemented the registration and publishing of different data source .We provide services for different data nodes through standard Grid service interfaces and use XML to eliminate heterogeneity of data model from various systems. This platform can integrate different business systems into Grid environment.Secondly this paper discussed some popular technology framework based on Java and gives their merits and defects, after that gives a summary presentation of how to use them in this study. With using technology framework, the development of information publishing will be briefness.Aiming at the requirement of Information publishing, this paper proposes a design scheme of based on Grid Service technology, in which made a introduction of functions will be realized and how does this functions work. It mainly includes: gains data from different data nodes, parse these gained data, detaches the data architecture and it's expression use style sheet, implements the function customization use for reference of Grid Idea, implements functions of information publishing and management and function-customization of data service and data resource service on Grid data node.in the next place, this paper gives the discussion of detailed implementation of information publishing system which Stresses interfaces used in this system. Under the spring framework ,changing the implementation of interface only need modifying the configuration file which makes upgrading system easily. The information publishing System realized by this study based on Grid provided friendly interface and is easily to use.
