Design And Implementation Of Public Rental Information Management System Based On Java EE

With the rapid development of economy,the industry is developing rapidly,and the typical representative is the real estate industry.Behind the rapid development and prosperity of the real estate industry,higher and higher housing prices have resulted in the inability of low-income groups to purchase houses,resulting in a series of problems.In this big background,the cities to speed up the construction of public housing,through the investment of a large number of rental housing to relieve urban low-income groups and new graduate community living,it is difficult to make contributions to create a harmonious society.Public housing the whole application process requires strict audit,cost is higher,the whole process of human work at this time the information management system can effectively reduce the workload,the whole application,review,announcement etc.Most of the process can be done through the network,greatly improve the efficiency of public housing management.In the development of public rental information management,the main content of the system is to implement the system according to the way of software engineering implementation.The first part is to analyze the application background of the system and give the status of the system.In the part of system development,the primary demand analysis is the content of the work,the software developer to communicate with customers,determine the system need to develop a business function,business function mainly through use case diagram of UML modeling,the functional requirements in terms of narrative,and performance requirements of the system is given,the entire system response time of narration,the demand such as concurrency value;For the whole public housing management information system technology were analyzed,and the system development platform for the Java EE platform,the corresponding page logic,business logic and data processing corresponding techniques are divided into a JSP development technology,the Spring framework and Hibernate framework,finally a My SQL database for description of data information is stored;In system design phase,around the demand analysis the content of the development,carries on the system overall design,the main work includes many aspects,the first is the system architecture design,detailed describes the system’s operational layer,business logic layer and data layer three layers architecture development content,in the network system architecture design,comprehensive comparison the characteristics of C/S and B/S development after selecting B/S network architecture for development,in order to promote the security of system,gives a safety design content in detail,the database design,system data clearly information storage database entity,the next step is given in detail the content of the database table design;For system design,after entering into the system of the core chapters,around the requirements analysis phase to determine each business function modules,including property management,security applications,security audit,data management,statistical analysis and other business function modules,using flow chart,sequence diagram,class diagram,including the business logic of the function module,gives its realization process in detail.Let public rental business information management system function module after requirement analysis,system design and realization,finally carries on the system test,mainly includes two aspects of functional testing and performance testing,test results show that the system conforms to the development needs,can be brought to rent the application process for effective organization and management,so as to enhance the management efficiency of the business.
