Public Security Information System Data Integration

Police information systems in the construction process, because the restrictions on the historical conditions, the public security departments of the business application based on the specific needs of different systems and different public security building business applications, it makes the application of a variety of public security services systems and database systems exist in the interior of public security. Therefore, the public security services of different application systems in the data extraction and integration, full use of already existing data resources and technology to build a sustainable, comprehensive data integration platform, has become a public security information technology issues to be resolved.This information from the public security system the actual situation, the theory and practice of engineering in close combination with the public security services have different timeliness of suspected cases of requests for information objects and a unified focus, using data replication, data mediation, data federation and data migration technology to achieve data integration, and finally to the data integration problems encountered during the adjustment and optimization.Firstly, the data integration related technical analysis, data aggregation techniques are introduced and the data set technology, and points out the Web services technology strengths in data integration; and public security information system data integration needs analysis; then made according to the demand of the public security information system data integration design, using different data replication technology to support the suspect object information with the public security information system in business information exchange system to achieve the suspect object information distributed applications, to ensure that the mutual information the accuracy, completeness, consistency and timeliness and other requirements; final paper on data integration to optimize the various interfaces, and proposed specific measures for the optimization and adjustment.
