This system use the UML object oriented Moduling technology and carry on themoduling analysis, find the usecase and actor of the system, and use the usecasediagram, the class diagram and the sequences diagram...etc. Emerged clearly structureand each part of relation of the system. This system take added value tax ratepaying asan example, use usecase diagram to describe the function of the system from the angleof the customer, point out operator of each function, also describe the condition andinformation stream of usecase, let us to understand system operation process clearly.This system use class diagram to construct the static state model of the system, findthe related class of system, detailed describe the attribute and operation methods, anduse the sequence diagram to express the information transfer and logical controlamong classes, Thus construct the dynamic model of the system. The rtepaying declaration system based on Web, adopt the architecture of B/S( Browser/ Server), separate the Web server, the application server and the databaseserver, adopt three layer structure models of J2EE, it is composed of the presentationlayer, the application layer and the data layer.
