Research And Implementation Of Topic Oriented Data Virtualization Technology

With the development of information technology,in daily work and life,people gradually realize the importance of data.In the field of government work,a lot of data business has been carried out.A lot of heterogeneous data are generated in the business,but due to the lack of unified data standards,the data sharing and exchange ability between various systems are poor.Such a large number of "data islands" were formed,which is not conducive to the development of government data business.At the same time,the feasibility of reconstructing the old system is low.Based on the above background,this paper proposes a topic-oriented data virtualization technology,designs and implements it,and verifies it in government related fields.The main contents of this paper include the following three aspects(1)This paper proposes a service-oriented data sharing and exchange model,establishes the connection between the original business systems in the form of services,and proposes a three-tier structure model of view-share center-service.Among them,the service layer is responsible for the interaction with the original business system,the share center is responsible for the data sharing and exchange between services,and the view is responsible for the interaction of the business layer,which reduces the system coupling and helps to carry out the data sharing and exchange business.(2)According to the actual business theme scenario,the data sharing and exchange model is materialized,and the related data virtualization system is designed by using data virtualization technology.System users can use a virtualization system to customize related theme data sets according to relevant business requirements,which solves the problem of theme business data sharing and exchange.(3)Based on the actual business application scenarios of the Federation of industry and commerce,this paper implements the application of the designed data virtualization system,and completes the related optimization work on this basis:using the distributed virtualization data set to solve the problem of data set integration at all levels of the Federation of industry and commerce;using TreeCode to code the data set resource directory to improve the query efficiency of the data set.In this paper,we use the data virtualization technology to design and implement a topic-oriented data virtualization system,which can solve the problem of difficult data sharing and exchange in government data business through application verification in relevant business scenarios.
