Research On Data Migration Methods Of Government Afairs Cloud

With the continuous progress and in-depth development of informatization,how to apply modern information technology to government offices,improve government service management capabilities,and provide better and faster services to the public have always been the focus of the government's functional departments.In the course of the construction of the government affairs cloud,the development of the mobile Internet has made the data exponentially exponentially,the finer service and management requirements,the gradual concentration of information systems,and the higher requirements on the performance of the system,the upgrading of the software system.Imperative.With the demand for government-level cloud construction at all levels of government in China,it is necessary to migrate in-use application systems,information data,etc.to the newly-built government affairs cloud platform.The new,more powerful system will replace the existing information system.From the development environment to the operational environment,when the low-level database is converted to the high-level database,the data must be migrated and can run normally.Data migration becomes an unavoidable issue.The government cloud data migration process is bound to face Many risks and the selection of corresponding methods are currently an important research topic and need to be solved by the data migration method adapted to the actual situation of government affairs cloud construction.Thesis introduces the background,significance,current situation and basic concepts involved in data migration and government affairs cloud.Take Yunnan Province's new “Cloud above Cloud” government affairs cloud platform as an example,and according to the construction of “Yun Shang Yun” project of Yunnan Province Information Center.Background,project positioning,construction goals and system architecture,and an exploratory study of the government cloud data migration method.Focus on the preparatory work for the data migration project of the Informatization Center,the design research work and the determination of the migration method,including the investigation of the status quo of the informationization of various functional departments in Yunnan Province,the basic analysis of the five major databases,the integration of data migration technologies and data Risk analysis of the migration method.This method provides a theoretical basis for data migration in multi-department and multi-system massive data involved in the construction of government affairs cloud platform,and has certain reference for the determination of similar data center projects in China involving data migration methods.significance.
