Research On Housing Security Decision-making Data And Its Sharing Model Under Large Data Background

Housing is one of the basic elements of human survival and development,the government provides affordable housing related to social stability and economic prosperity.Currently,due to the supply and demand sides of information asymmetry,leading to a mismatch between supply and demand as well as the low utilization rate of affordable housing highlighted the limitations of housing security-related policy formulation,implementation effect of housing security needs to be improved.It should be noted that in the moment of an explosive increase in global information,fully use of big data resources to improve the housing security decision-making ability,give full play to the effectiveness of housing security benefits provides an important way.However,the data sources related to housing security scattered,many types of data,data standards and large scale makes housing security data integration and sharing difficulties.Based on the above background,this paper focuses on the goal of scientific decision-making of housing security,starting from the three aspects of housing security decision data demand and housing security decision data sharing and sharing model verification,to solve the problem of what data and how to solve the problem of data distribution,heterogeneity and mass.The main contents and achievements of the paper are summarized as follows:Firstly,demand for housing security decision-making data,to build housing security decision-making data indicators.Housing planning is an important guiding document,to strengthen urban housing construction,reasonable housing supply structure,meet the residents of the housing needs of different levels.This paper builds up the housing security decision-making data system from three aspects: the housing security situation of the last planning period,the characteristics and status of the housing security demand object and thegovernment support ability.Secondly,build housing decision-making data sharing model HSDDSB.Based on the analysis of the problems of data sharing in housing security decision-making,this paper proposes to use HBase as the blackboard database,choose HDFS as the control mechanism management library,realize the integration and sharing of housing security decision data,and solve the massive shared data Storage and data sharing security issues.The paper chooses Web Services technology to solve the problem of sharing data types and different standards,and realize the seamless integration of multiple data sources.And with the Quartz scheduling management module,through Quartz call all the Web services in order to obtain timely data sources in the updated data resources to solve the problem of shared database data update.Thirdly,build a development environment,simulation experiments.This paper tests the validity of the decision-making data sharing model of housing security,and builds the development environment to test the model.The paper analyzes the decision-making data of housing security,including housing security situation and housing security demand object and government support ability table for database design,and realizes sharing data acquisition.
