The Design And Realization Of Police Population Information Relation System

The information era public proposes the request security organs to informationize.Only if we make full use of the resources of public security organs and integrate the public security organs with information means,can we prevent and crack down on the criminals and outlaws.Therefore,under the current circumstances,it is necessary to dig out a information management system,which is information sharing and is favourable to the integration of resources for the public security organs.On the basis of the business and the user requirements of the information management of the public security population,this thesis use the method of information association to make data analysis,which makes the association between the information that separately stored in different information systems.This achieves the function of related query,retrieval,and deeper analysis and utilization of the general information.The main research contents and results are as follows:(1)Based on businesses and user needs,the system is divided into data extraction,information association,unified login and user management,and use cases are designed using the object-oriented design methods.(2)Based on population information related needs,this thesis designs the overall architecture of the system,and has carried on the design to the four major function subsystems and database.The ETL job achieves the data acquisition of the population information,and a unified view of topic information is realized through the ID card number.In the information correlation model,this thesis designs a set of data conversion models and such correlation models as association,same name relevance and synonym relation,to establish the relationship in population information.(3)The implementation of public security population information system.This chapter expounds the implementation process of the public security population information system.We realize security population data extraction using three processes:data extraction,data buffer and data processing.We also study the correlation model of the public security population information and design data conversion process.We still achieved correlation system of the public security information using integration methods,and has carried on the demonstration and application.(4)Integrity testing of the system.Function testing are tests of page operation specification and the critical needs of the four subsystems.Performance testing tests mainly on system traffic and clicks.This system realizes the connection establishment between the public security population information system with business models,improving the ability of public security information management,which is of great significance.
