This system use class diagram to construct the static state model of the system, find the related class of system, detailed describe the attribute and operation methods, and use the sequence diagram to express the information transfer and logical control among classes, Thus construct the dynamic model of the system.(4)Using PKI Security Technology based on digital certification to solove the satety prolem of Electronic Tax Revenue System.(5)Useing the Three-tier architecture based on J2EE and MVC design-pattern to develop the Electronic Tax Revenue System.This system has been successfully used in 10 revenues, banks and taxpayers in WUJIANG.
