The Design And Implementation Of Hangzhou Economic Census Database System

With the rapid economic and social development, social statistics, especially theincreasingly high demand for timeliness and accuracy of economic data, survey of the past by alarge number of human resources, such as publishing the closing table, auditing,logging,duplication and re-examination of investigation units statisticians, investigators,statisticians, etc. together with the completion of this is very easy on the intermediate links,omissions, indicators dislocation units of measurement mistake and error, and the current surveyobjectsalso undergone a sea change, whether it is structural change or increase in the number ofsurvey mode to feel the pressure, the timeliness and accuracy of survey data into a bottleneck.Especially once every five years, the country’s largest Census-Economic Census, the survey isat all levels of society as a whole organs, enterprises and the self-employed, only Hangzhou,there are nearly110,000of the investigation unit, involved in agriculture, industry, construction,finance and statistics sectors20, the type of statistical investigation forms of172class, surveymode greater human and material resources will be wasted, but the effect is very satisfactory.How to combine the existing science and technology, rapid and effective census survey, and asimple and accurate management of survey data, a true reflection of socio-economicdevelopment of the actual situation, and provide strong support for leadership decision-makinghas become the common aspiration of the current statistical work and social. Therefore, theeconomic census database system design and development of a scientific development of thesociety as a whole has very important significance.In recent years, various places of the country are steadily advancing statistical informationconstruction, continuous improvement through a variety of technical methods to submit thesurvey methods and data processing mode, such as the excellent straight-line reporting system,integrated database system, system programs are the future of statistical informationconstructionand development direction. Departure from the research background and outside the status quoon the weak links of the current census, fully focused on the statistical theory and the theory, in-depth analysis of system functions, modules, and the demand on the system performance andoperating environment. and the overall system architecture design. Through the comparison of B/S structure and C/S structure model, described in detail the system uses the advantages of theB/S three-tier architecture model design and build the user application layer, business logic anddata layer to the concrete realization. The same time, through the user’s point of view, a detaileddescription of a running instance of the entire system, including detailed testing and validation ofthe various functional modules of the system and system performance assessment, system designand has a high significance and real-world applications value.By reading a lot of technical literature and the more advanced database systems, to furtherclarify the focus of the work of the system design: First, to establish a simple and easy-to-usenetwork data submitted to the platform, to improve the artificial submitted; is to establish asystem management modulestrengthen the management report and audit logic; strengthen theyuan against the database management, to further standardize the statistics object data class ofstatistical standards and statistical indicators; establish and improve the data query pooledanalysis module, to improve the efficiency of data mining, real-timereflect the trend of economicdevelopment; five to do system testing and review the work, repeated verification of eachmodule, and to develop the next step improvement plan. Module simplifies data source of thedata submitted, to speed up the census data acquisition speed, strengthening the automaticconstruction of the system, greatly improving the economic census data acquisition platform anddata summary submitted by more than five-part work, the network data analysis, summaryefficiency, while the ER model of the system data layer design, census data tables, and logicalrelations institutionalized method can be modified for different periods of the census and demand,not only strengthened the unity and versatility of the system, they do data only, andcomprehensively improve the accuracy of the economic census data.
