Based On Sdo Data Access Model And Application In Data Integration

With the deepening of China's information industry and development, companies are using their own established business information management system. With enterprises, departments of business contacts, information sharing is the primary problem, therefore, companies must face a large number of heterogeneous data. However, traditional distributed database interface is not due to its flexibility and easy scalability of heterogeneous data can not be effectively resolved.Thus, in this encounter a problem is:What method can efficiently and accurately, the flexibility to deal with heterogeneous data. After years of development, we found that service-oriented (SOA), enterprise application integration framework can provide a dynamic, scalable architectural approach for business and IT to provide unprecedented flexibility and cost savings.As we all know, SDO architecture is the SOA architecture of the "iron triangle" is one of IBM and BEA jointly released a new data programming specifications, focusing on areas of heterogeneous data integration. In this context, this paper will SDO architecture technology to collaborative R & D project "SDO-based data integration platform for social insurance", the aim of involving the social insurance business in all areas of information and data into a standardized protocol in the common platform to address the current social insurance Jiangxi multiple information silos, can not effectively sharing information and other technical problems.This paper introduces the problems raised by XML and Web Service middleware technologies such as the traditional principle of distribution of data, heterogeneity, and an overview of SOA-related knowledge; Secondly, the detailed analysis of the SDO architecture and based on the concept of service and its implementation techniques; again, in the three-tier architecture layer of the middleware layer and the middleware proposed combination of SDO data integration methods, choose the right middleware development environment complete coding; Finally, the SDO-based heterogeneous data integration applied to social insurance programs Jiangxi data integration platform.
