Research And Application In Data Integration Based On SDO Data Access Model

With the deepening and development of China’s information industry,enterprises have established their own business information management system.With the corporate business dealings between departments, information sharing is theprimary problem, therefore, companies must face a large number of heterogeneousdata. Heterogeneous data integration plays an important role in the process ofenterprise development, which integrates various heterogeneous data integrationsystem has become a very important technology. Because enterprise systems usingdifferent data storage formats, database types in various stages of development, dataintegration and therefore to bring some technical difficulty. Heterogeneous DataIntegration After years of development, has formed a number of solutions andindustrial products, such as federated database technology, data warehousing, XMLdata integration, data integration service-oriented approach and other related theoriesand the method in which service-oriented software methods recent rapid pace ofdevelopment, has attracted wide attention. Service Data Objects is under an integralpart of a service-oriented architecture, logical representation of heterogeneous dataconcerns, service-oriented approach enables a unified form in terms of datarepresentation. Service-oriented approach to heterogeneous data object underlyingheterogeneous data were masked, providing a common unified data access interfacefor each of the different data sources, so that programmers can easily use a variety offrameworks and tools applications to access.This paper describes the principles of XML and Web Service and othertraditional middleware technology, heterogeneous SOA-related knowledge andoverview of the distribution of data; Secondly, based on a detailed analysis of theconcept of SDO architecture and services and their implementation technology; onceagain, in the three adds a layer of middleware layer layer architecture proposedmethod SDO data integration middleware technology combined with selectappropriate middleware development environment to complete coding; Finally, theSDO data integration technology in Jiangxi security Department projects.
