Research Heterogeneous Data Of Manufacturing Industry Intergration Based On SOA And XML

Heterogeneous data intergration play an important role in the informationize modern industrial,and ingeegration of various heterogeneous data has become an important technology. Enterprise systems are developmented with different data storage format in various stages,which brings some technical difficulties to data integration.The technology of heterogeneous data integration after years of development has formed a number of solutions and industrial products, such as the federal database technology,Data warehouse, data integrate based on XML (XML extensible markup language can be extended relatively Language),data integration adopted service-oriented and other related theory and methods, service-oriented software approach recently has developted rapid and has attracted lots of attention. Service Data Objects (service data object) is part of a service-oriented architecture,which concerns about logical representation for heterogeneous data, that enables service-oriented architecture has a unified representation for data representation. Service-oriented data objects shields the technology of underlying heterogeneous data,and provides a common unified data access interface for each different data sources, so programmers can easily use a variety of frameworks and tools to access the the heterogeneous data in application. In this paper, we compared and analyzed products of heterogeneous data intergration and various theories on heterogeneous data intergration, learned theories and techniques about service-oriented architecture.We expansived the function of data access layer which includes in service-oriented, which makes us can access relational databases in an uniform by using Hibernate to manufacture the ralational data, and applied practical systems.In this paper we deal with heterogeneous data from different databases,and the key problem is the integration of heterogeneous data sources. By using service-oriented data representation, representate the heterogeneous data in the form of a data graph, representate data graph by xml,that shield the form of underlying data, visit data using service-oriented data interface.
