System Integration Application In Public Security Information System

Along with the public security information construction, its business serviceincreases unceasingly, which caused the newly built information system and theexisted old system to form the information isolated island. It is very difficulty for theintereonnection and the intercommunication of the information.This kind of conditionhas caused the massive building redundant projects and the resources waste, whichhas seriously restricted the public security system informationization constructionmight and the effect.The close union of the theoretical analysis and the topic research is the presentpaper characteristic. The present paper take the Shanghai police information system asthe central system integration development. This background has carried on thediscussion and the applied research to the system integration realization technology. Itcontains how to realize the data sharing of the heterogeneous database with the linkservice and the transparent gateway technology, in oreder to provide the convenientconnection of UTOI's interface; how to realize the office automation system'sinquiry of the UTOI based on the Web Service; how to realize the UTOI'sdistributional application of the public security information system with the differentdata duplication technology, with the need of the interactive information's accuracy,integrity, uniformity and timeliness and so on;how to effectivly use the ETL(extraction, transformed and loads) process to realize the data migration from theUTOI to the statistical of the case system.
