The Architecture Of Nanjing Police Affairs Integrate Application System

Public Security industry is one of the first computer application to put day-to-day job, one of the industry. However, the Public Security Bureau in the early applications only a simple data query functions, data entry as soon as there is no system to update their data only as an archive to use, for public security personnel should not provide better information to support. With the development of time, the public security system step-by-step set up, the applications should not share the data, forming a so-called "information island." Applications to address the public security "information isolated island" problem, "General System" concept and set about the use of platform implementation, the actual work at the "integrated system" to increase the practice of theoretical models.This article first applications of X City General of Police to carry out general introduction, the design goal from the beginning, careful consideration of the actual application environment, the implementation of the software technology platform for police after a comparison made after the selection.Introduction was followed by police in X City General applications software technology architecture, starting with the introduction of multi-storey Delphi application structure as bedding, and then extend the application of the X City General of Police to adopt a multi-tier distributed system architecture. For one of the core GIAP (General Integrated Application Platform, an integrated application platform for general-purpose), using a "browser application server + + GIAP commercial middleware + web-based database" four-tier application framework. Good solution of the problem are as follows:(1) resource-sharing pool(2) multi-user concurrent access to treatment(3) the transfer of load balancing and failure(4) zero client maintenanceGIAP platform will be B / S and C / S combination of the two modes of operation, the Web, Delphi, Java an organic integration of multiple technologies. With the popularity of WEB, and WEB-related technology is also widely used (such as WEB Service, Soap, WDSL, XML). According to years of development experience, pure WEB system in the treatment of complex interactive interface convenient and flexible than Delphi, and Borland's Delphi has argued that products can be cross-platform, but it is limited to Windows and Linux, to run at large in a variety of Unix operating system environment, Delphi applications and technologies not as good as Java. Therefore, GIAP three technologies will be combined, the strengths of the three cleverly combines organic. It also has a set of Service Backgrounds procedures forward disaggregated Units provide the necessary services such as data services, message services, statistical services, auto-matching services, portal management services, system maintenance services, all of these procedures were entirely Services in accordance with the J2EE specifications, 100% Java implementation. Therefore GIAP run at the application server implementation class with the software and hardware platform-independent features, can be present at a variety of hardware platforms (PC and minicomputer) and operating system platforms (Windows, Linux, Unix) to run on.And details of the communication system platform GIAP protocol, data packets from the protocol package format to start the whole introduction, and then introduce the bottom of the core system rtlapi.bpl, giaprun.bpl and some core pasapi.bpl such as dynamic link library function and logic flow. Finally GIAP introduced elements of key technology platforms. The author participated in one of the design data model to discuss and formulate programs for the secondary development platform data module and the definition of data Designer has been improved.Police re-introduce the X City General data applications design, population, respectively, described in detail the case of data structure design and data structure design, one of the structural design of the case data, including data on the design of suspects, victims and witnesses of data design, data design and units involved in the case involved in the design of items of data. X City, then the police also introduced an integrated system safety design, but also detailed the functionality of the system's introduction of the Overview. In this paper, the author of the implementation of the administrative case file for data acquisition, business management and administrative cases and administrative cases the development of legal instruments such as the production function of the job, and General of Police in X City in the late application system service procedures involved in the background of the maintenance and performance problems analysis and treatment, to participate in the application server and database server performance tuning.Finally, police in X City General applications and prospects for concluding that the run-time problems and possible solutions.
