The Data Integration Model Of XML And Web Services And Its Application In Educational Testing Information Systems

Integration of educational examinations, which means take full advantage of theinformation in computer and network technology, integrate and adjust variouseducational examination system in use, make information resources can be sharedbetween different systems and allow automatic synchronization of data resources inreal time. The implementation of education exam information integration projects cansimplify education workflow, improve efficiency and primary prevent “islands ofinformation” from generating. Ideal data integration platform, in principle, can shieldthe heterogeneity of various architectures, provide the service to accessheterogeneous data. Without changing the storage and management of the underlyingdata, it can achieve interoperability of the distributed heterogeneous data, enhance theflexibility and applicability of the system.Based on the analysis of three classical data integration architecture, the paperfirst study the integration of data based on middleware technology. In-depth analysisof RPC-based middleware technology, ORB-based middleware technology andMessage-oriented middleware technology. Then through the analysis and comparisonof design data integration model based on XML and Web Services, the paper detaileddesigns a XML-based data exchange model and a Web Services data integrationframework, and gives the key technology implementation strategy.Finally, the paper gives the detailed solutions and the key achievement of theeducational testing information system data integration, based on designed XML andWeb Services-based data integration model. The solution proposed in the hope that itcan play an important role on constructing various Jiangxi education examinationsystem exchange data integration platform, better promote the further development ofour province’s education examination information technology.
