Design And Development Of The Information Resource Of The Government Affairs Shared And Exchanged Platform Based On J2EE Frame

With the development of society and information technology, peoplehave greater demand for information; meanwhile more rely on the network.People haven't been satisfied with browsing information and gaininginformation on line, however, want to express the opinion and inquire thedata more, etc. Moreover, the formation of E-government platform makes itpossible to work on line that people are always dreaming of.At the background of national economy and social informationize,E-government is a system solution which shifts government functions ofinformation release, management, service and communication into theinternet, which is the aim of raising office efficiency, improvingdecision-making and investment environment of government. In the meantimeE-government also provides the systems that combine with Management ofGovernment Process Reengineering, Construction and Optimization of theInternal Management System, Decision Support System and Office AutomationSystem that offer strong technical and advisory support for the improvementof government information management and service level.This paper has been mainly written the information resource of thegovernment affairs shared and exchanged platform, Both e-governmentplatform.it researched the two most important part of e-government,data shared and exchange,and application system Access.Data shared and exchange divided into two types: Landing data and NotLanding data. Landing data means: building a shared database on the shared platform.Implementation exchange through the shared platform between eachdepartment.The data for exchange is stored on the basis database throughthe shared platform. Formed the basis data of the need to share . Buildinga shared database in two stages. The first stage: Data mirroring. SpecificImplementation is to copy the data of each department to informationdatabase of Xicheng District Information Office.The data in this databaseis Primitive.The second stage: Basis on the mirroring, comparison andscreening the data,form a new shared database.The data in this databaseis Processed. There are two ways the shared database access to data fromvarious departments: push and pull. Push means maintain a high degree ofdistrict platform between Shared data resources and Source System.Exchange system to take the initiative by the exchange source services.Platform updates after receiving data immediately.Pull means Districtplatform Apply the necessary resources to the departments. Then the datadirectly from the provision of resources from Provider.Not landing datameans departments apply a transparent peer-to-peer exchange through theexchange platform.Data of exchange is not stored in the node of exchangecenter. This pattern in fact established a data exchange or exchange accessBus.Exchange of not landing data divided into push and pull two models.For some application system of need to share resources. If the data hasno requirement of real-time. Or the volume of data is particularly large,or because security ,management, and other reasons for the platform toshare information regularly released. Such an exchange model register thetime for data exchange by the platform. By the time the platform will takeinitiative the shared data to demand for resources. We also call this model push model. Application system of resources requirement node initiatedrequest, exchange system will submitted request to the platform databasemodule. After the module of database verifies the legal authority asked,theresources asked are recycled back to to the resource applicant throughexchanging services of another time. This kind of exchange mode brings inlooking from the platform,it seems to pull the Data Resource by demand forresources. Therefore, also Called "PULL" exchange.Data exchange system as a whole acts as a virtual centre database, atthe same time like a switch. Ground floor that whole data share and exchangerealize and store mechanism employ node transparent to every. Thisstructure is loose coupling, like star network, it is very apt to expandthe level structure, construct out the multistage data-switching systemstructure, in order to support more broad wide area scheme.The E-government is a revolution of government's management style. Itnot merely means government's information is further transparent andcoming into the open, and mean the government should manage its one thatadminister and manage the affairs publically by network. The most importantintension of the E-government is the organization demarcation line of usinginformation and communication to break the administrative organ, constructa fictitious organ of electronization, enable people to obtain informationand service of the government from different channels.The E-government is right to accelerate government's modernizationpaces, information-based level and service development level of promotingthe whole society play a key role.Though the actual system has already been developed and finished, butin the real work, we should accomplish " develop lightly, application heavy "; Manage lightly, service heavy ", More offering form download, Apply onthe net etc. to bring the online service of more value to the public, butnot only introduce static information such as the policies and regulations,contact way. We want to reduce reduce the appearance with true E-government,build E-government with Chinese characteristics!...
