The Design And Implementation Of Group Monitoring Platform Based On Javaee

With the gradual implementation of urbanization in the society, the urban population is growing to an ever large extent. At the same time, with the rapid social and economic development, a lot of commercial centers, office spaces are built to accommodate such high population density. Businesses companies are always in pursuit of high population density and large population flow rate, in its effort of pursuing optimal profits. However, it is difficult to prevent the crowds from stepping on each other due to emergencies caused by panic and dangerous behaviors in these public gathering places. An efficient and accurate public abnormal behavior monitoring platform is needed to monitor the specific places where the crowds gather.In addition to meet the requirements of crowds abnormal behavior monitoring about daily population flow density and emergency situations warning, some other requirements are raised like more stability and good compatibility, for future business improvements and system upgrades. This paper uses the mature JavaEE platform to realize these requirements. The JavaEE platform has good peripheral compatibility, proven solutions and a good upgrade compatibility, which can meet all the requirements of crowd abnormal behavior monitoring.The system uses object-oriented development methodology. A detailed analysis and design are provided based on B/S three level architecture, in accordance with the idea of workflow for systems management, communications interface module, and query statistics module. The technology used in the system includes JSP, Servlet, JDBC, EJB and so forth. Among them, JSP and Servlet are used for the presentation layer, which is responsible for producing the view, to provide users a flexible, elegant page. EJB is mainly used for the logic layer, responsible for handl ing the problem of monitoring the business logic and data persistence. And the JDBC is used to operate the database access of the Java programs.
