Design And Realization For Real Estate Surveying And Mapping Management System Based On Patch Algorithm

To implement the outsourcing company management and the surveying and mapping business management for real estate registration office in a city,the periodic patching algorithm is used in this paper which has realized surveying and mapping data audit management business based on generic products and core business middleware.At the beginning,the patch algorithm or the periodic patching algorithm does not design comprehensively,which contains the effects of various factors on the performance of the system.Under certain some conditions,those two kinds of algorithms can reflect its superiority.Including the period constants PERIOD geographic information data flow value,surveying and mapping business documents in geographic information system on their own load ratio and resource allocation priority strategy.Although the cycle patch algorithm for improved control of the traditional patch algorithm to be randomly generated in the defects in the system of geographic information data stream,but the system generates control blind patch stream is obviously inadequate.Once the user request to a file mapping business is too frequent,there may be a system generated over the patch stream,the system performance will be affected.After the study found also to cycle patching algorithms using cycle grouping method of optimization,thus puts forward the cycle patching algorithms for each geographic information data flow between the cycle time interval of packet time idea,the system in each packet time period generated a shared patching stream,request in all the packet time period had sharing patching stream to provide services.In this paper,ASP.NET is used to implement the system display interface,data operation and background logic.To ensure good expansibility and maintainability of the system,the network architecture and architecture of the system are designed in this paper.At the same time,the design of system function is combined with system structure.The five function modules of the system are the surveying and mapping business management,the external management company,the result data management,the real estate data audit and the system management.In order to ensure the performance of the system,the system data logic,which can ensure the complete design of the system,is designed by the system access security and the data storage security.This paper uses ASP.NET and other related technology to realize the function of the module,which is based on the detailed design of the system and supports the management function of surveying and mapping data audit.To verify the actual system performance,according to the function test and performance test of function and performance of real estate surveying and mapping data audit management systema are detailed test.The test results show that system has achieved the expected function and performance requirements.
