Design And Implementation Of House Purchase Information Management System

House purchase information system is a sharing platform,targeting to real estate companies and independent individuals,which can aggregate the information of real estate enterprises and provide information about buyer's purchase demand.Real estate enterprises can dynamically publish the information of housing source on the platform,carry out brand housing information and rental housing demand,and online questions.It is also possible to retrieve requirements from mobile phone or a computer client,master the dynamic of the target property,achieve comparison quickly and easily,and find satisfactory house easily.The system can not only satisfy product publicity and sales for real estate enterprise,conduct research on dynamic demand of target population,learn about competitor situation,reduce manpower and material expenditures,and achieve a multiplier effect,but also greatly reduce the burden on individuals to rent and sell homes,realize online rental like ordinary goods.The primary task of system design is a clear design goal.Designed to find a suitable design method,and further to develop the corresponding specified the whole design of the primary and secondary module;primary and secondary according to the function of the system design will be subdivided into a plurality of levels of functional modules,each module determines the function to find the software design correspondence relationship,call relationship module,determining the corresponding interface module and the module to complete the transfer of information between the modules.To avoid large amounts of data redundancy,to ensure the quality assessment module partition,paying particular attention to the design structure of the interface information.Since the inquiry application services and user access is achieved through web services,so pay attention to design Web services portal.Among them,data-related services,application services and a single composite business services are supported by the underlying SOA architecture will ultimately reflect in front of the user,the system will use a single point of unified portal management technology for different services to achieve logged in,different set of business applications together.The system,adopting a dynamic creation method,is designed according to the principle of structured design.Firstly,we will establish an initial model of the application system,and then add and refine the sub-function on the prototype of the initial state,from the surface to the point,from point to side,through the continuous function module modification and the perfect cycle process,form an application system which is mature,relatively to complete and friendly to interface gradually.The purchasing management information system,using SQL query language,is developed with Powerbuilder9.0 database.The system can understand the dynamics of market listings,the target needs and changes of buyers through comprehensive and dynamic management of rentable and saleable housing information.Then the target customers and real estate companies,intermediary companies to reach an agreement.Thus,the whole process of buying and selling the house is completed.
