The Design Of A City Development And Reform Commission Price Monitoring System Based On J2EE

Price monitoring is one of the most basic and important work in the government's price work.With the rapid development of information technology,the popularization of computerization,and the advent of the era of big data,the amount of monitoring data has increased sharply.Strengthening the construction of price monitoring system network and information release has become an important way for the government to supervise market changes.Based on the actual work requirements,this paper summarizes the characteristics of municipal price monitoring department,summarizes the problems of similar price monitoring system,analyzes the needs of all levels of price monitoring department,and designs and implements an online price monitoring system based on J2 EE architecture.Five functional modules are designed in this system: price data receiving module,price data query module,price data release module,price data analysis module and system management function.This paper use J2 EE technology as the architecture to divide the whole system into presentation layer(Struts),data persistence layer(Hibernate)and business layer(Spring).JAVA language is used as the main programming language and Internet as the carrier(government special line).After comparing all kinds of mainstream databases,Oracle is adopted as the system database.This system integrates the functions of similar monitoring system,and adds special function modules according to the specific needs of a city price monitoring department,and designs Tomcat log self-cleaning program and unique database optimization method to improve the problem of "long-term use of required card" in similar systems.The system described in this paper adopts the modular,structured design concept,the price monitoring work is divided into different functional modules for development,improve the flexibility of the system,and carry out in-depth module customization,provide a general,complete secondary development interface.The system focuses on the simplification of data reporting process and the control of data authenticity.Be able to analyze and process the reported data;The release of processed data is optimized to make the monitored data more reliable,so as to meet the accuracy of the general economic index calculation by the price monitoring department and the authority of the data supported by the municipal government's macro-control.
