Design And Implementation Of Urban Public Safety Systems Based On SOA

City to respond to natural disasters, unexpected security incidents, traffic managementand major epidemic diseases, emergency treatment system, to effectively ensure the city’snormal social order and life, play an important role. However, when these systems are indevelopment and construction, mostly for the needs of a particular area for development,independent of each other between different systems, mainly in the resource can not sharedover a network, database structure design inconsistencies, the data format is not uniform,different systems can not achieved between function calls and other issues. However, inpractical applications, in the event of natural disasters, social security problem is likely tooccur, while transportation and medical problems will arise accordingly, thus requiring eachsystem to achieve the linkage, to share resources with each other, thereby further protect thecity’s public safety. Currently the city public security architecture of the system cannot meetthis demand, and re-establish an integrated system will develop a waste of existinginvestments, so to integrate the different existing systems is a better solution.In the current urban public safety systems based on the research and analysis that cannotbe achieved between the various system functions call each other, sharing data with eachother and other issues, proposed the use of the soa model to build an integrated platform forthe integration of urban public safety idea, the use of surface technology to the servicestructure means the existing sets of the current public safety systems into the same platform,the integration of heterogeneous systems and the integration of heterogeneous databases.Integrated Platform to be the main route is the use of technology. NET FrameWorktechnology, software engineering-related ideas under the guidance of a platform for building service-oriented architecture systems, the interfacial layer rich interface using SilverLighttechnology architecture, user experience, but also conducive to the deployment of the clientsystem, the database service layer, using the ADO.NET Entity FrameWork technology toprovide data services, business software layer technology to build platforms using the WCFservice, and remote communication mechanism, and ultimately completed in accordance withthe SOA model to build an integrated platform. Technical and technological research in therelevant part of the discussion of system integration technology, SaaS model theory,service-oriented architecture model,. NET FrameWork development, etc., as a platform to laythe foundation for the design and implementation; in the needs analysis section, for thecurrent public safety emergency system integration requirements, for analysis using theUnified Modeling Language; part of the overall system architecture design, the use of fivemethods expounded the view of the overall system architecture; in specific parts of the designand implementation, the use of. NET FrameWork related technology, the system the mainfunction.
