Research Of Heterogeneous Data Integration Technology And Its Application In College Orientation System

As with rapidly development of computer and technology,so will the information construction in various fields.The digital campus construction work has been put on the agenda.But as the construction process of developing,there will be some new problems inevitably.It restricts the development of the campus information.As in other fields,a large number of date has been accumulated with the digital construction of university.But these data are stored in different departments or different platform in the information system.So the phenomenon of data storage distributed and the inconsistent data format and data heterogeneous exists generally.It results in system data that can't be real-time synchronization.It is difficult for data integration and processing.In this paper,according to the construction of the actual information system and the new work flow,through the analysis of the current heterogeneous data integration development,it review of the key technologies and the characteristics of heterogeneous data.Then the analysis process of heterogeneous data is given in the system from the process of heterogeneous date integration in new system from the aspects of public data model,schema integration?query processing and semantic conflict,which ensure the integrity of the data function demand at the same time.It consists of the heterogeneous data SOAP.Web service technology integration solutions based on it.Based on this scheme,the reuse of existing business system resources and using service oriented architecture(SOA)effective integration of the business system.The realization of a heterogeneous data environment service platform.The system builds a scalable system framework which efficient response orientation work in all kinds of business needs.In the process of implementation,the system structure design,semantic conflict design,query processing and distributed transaction design are described in detail.It shows the whole design process.Finally,it presents the process of realization for the main function module of system.It realizes integration technology of the application of heterogeneous data in university enroll system.It analysis the achieve of the results.The system completes data integration business system in university enroll system and heterogeneous data platform docking and processing.
