Study on virtual database architecture of data integration;

Development of soft sensors for data integration in process industry;

The Research on the Data Integration for Personal Credit Management System;

The key technologies it used includs data conformity technology of TALKMAN DI, secondary development technology of ArcIMS, memory collection technology of RIA, combination of virtual simulation with 3S, as well as hydraulic model of flood inundation.

To solve the problem that application systems in current government are isomerous,collaboration and management difficulty and each other can not share resurce,this paper provides an efficient model,which is the platform composed of external and internal application and data conformity.

The data consolidation method based XML Schema is put forward in this paper,by the combination of model method based XML and pattern mapping method,pattern integration is realized,thus public pattern is produced,lastly,the mapping rules between public pattern and local pattern are created.

Key Problems and Solution of Distributed Data Integrating and Sharing;

By analyzing the diversiform storage of enterprise data and their mode, this paper presents the design and implementation of a data integrating and publication system based on web.

System access and data integrity process in signaling No.7 concentrative monitor system;

About the building of urban cadastral management information system,several problems of data integrity,data store and data of time and space will be preliminarily discussed.

System platform adopts mainly the settlement project based on the Web Service technology,namely,service structure centered on service;settles the conformity of database and the requirement of cross-platform,makes the stable foundation for digital campus building in the future.
