Design Of The Community Property Management System Based On Java Card

In the rapid development of computer technology in today's society,more and more smart cards are introduced to the property management system.However,in the present national market,most smart cards are developed by C language or assembly language,as a result of that,lots of developers would take lots of time to be familiar with the underlying communication protocol and they also need to define different instructions according to different programming interfaces.Thus lead to that the different development environments of smart card are not general,and each company's smart card can only be developed by its special development environment.What's worse,it's very complex to achieve smart cards' application porting for different companies.At present can be a very good solution to solve the above problems is the Java card technology,which is a combination of Java technology and IC card technology upgrade product.Its advantage is that it can solve the problem of many applications having influences on each other,and it is relatively simple,low cost of development.Aiming at the problems above,a kind of property community management system based on Java Card and B/S architecture,which is with low cost and convenient card application transplant,is designed in this paper.The system use the MVC development pattern,the upper machine management software is divided into individual module,user management module and the rights management module.In order to avoid the data update and insert anomaly,third paradigm database is used in this design.Through the study and the demand analysis of the system,the PC management software's fully function is determined.According to the considerations of actual demand and cost,low cost,functional card reader is designed.Due to the transplant of the system in this design is convenient,the development and transplantation of management systems,which include natatorium system and so on,is realized.PC management software and the slave compute were tested in this paper,the test results meet the design requirements and design effect,the stability and feasibility of the system is verified.
