Research And Application Of Unified Data Exchange Platform

Since long,with the division of Government department function,starting varies of the computer application system and lacking effective factors for unified plan and macroscopic instruction,the phenomenon of the present E-government application systems are absolutely with each other,the data standard are not unified and not able to share, and having massive information isolated island.Specially,the E-governmehts application systems which involves many departments,will construct a set of data exchange platform for each application in order to realize the exchanging and sharing of data,which induce building redundant projects and investment.Moreover,because defferent departments and different application systems use different data exchange platforms,the application systems are difficult to share the data,inducing the waste of information resource and the lower ratio of performance-to-price for construction.For solving the question of the present E-government about the data exchange platfrom,this articlee proposed the concept of "the unified data exchange platform",proposed the principle of design and the overall construction for the unified data exchage platform,realized three sub-modules of the exchange module,including extraction,the transmission and the load.At the same time,the article analyzed and realized each subsystem and related modules in detail.Indicated in the practical application that the unified data exchange platform has very good effect to solve exchanging and sharing question for information resource of various departments.Innovation points:1,"applications accept after checking into by only one point",namely in a physics's exchange platform realizes many"sub-platforms of hypothesized exchang".In order to isolate applications mutually, data exchange of different application systems does not disturb mutually, the included department can access to the different application through one pretage machine, avoided the building of data exchange platform repeatedly;2,Developed the procedure named "dynamic issue pretage machine node proxy" based on the principle of SNMP.The management station dynamic fundation pretage machine proxy procedure,operate every exchange pretage machine directly,but does not need to arrive personally various departments to deploy the procedure,which caused the operation and management of administrator becoming very conveniently;3,Developed and realized the data exchange mudule of supporting many applications,guarantee effectively reliability and security of information.
