Research On Heterogeneous Databases Integrated System Of Mines Enterprises Based On Web

Mines are a type of special enterprises which engaged in mineral prospecting and exploring. Mines have a large of heterogeneous system because of independent development and scarce of union standard.Aimed at the problem that mines have a lot of remnant databases and "Information Island" , this paper designs a mode which in favor of mines' heterogeneous databases integration. The paper constructs a Ping mines electronic commerce heterogeneous databases integration plat. The experiment is success. The model is designed expandable and distributed n layers B/S mode. Using Web Services as interface layer makes integration have expandability and flexibility yet.This paper researches the realization of the integrating system. It discusses the realization in detail. It includes the connection, save and taking, the elimination of the heterogeneous mode, client side realization, and so on. The heterogeneous is eliminated by the programmable components which are DataSet and XML and provide union data describe format. Used Web Services encapsulates affairs logic, shields the heterogeneous of data source and provide interface for customer application visiting Web Services. So subsystems can be extended to provide Internet/Intranet teleservices. The implement of client-side integration uses IE browser as union customer interface, and uses ASP. NET to program made client-side and mesosphere inosculating.Research of the paper is success. Mines constructing large-scale heterogeneous databases integrated system can use it for reference. It can direct other enterprises explore non-coherent coupling integrated system. The research has definite operation significance and economic value.
