Design And Implementation Of The Data Transmission Middleware Of The Campus One-Card-Through System Based On Web Service

The Campus One-Card-Through System is the basic project and the important part of the digital campus. Its useless will not only provide the convenient life for the whole teachers and students, but also greatly predigest the school's management and improve the work efficiency. Although the teachers and students have realized the advantage of The Campus One-Card-Through System, there are some questions in the system, for example, the data of the teachers and student between the card management system and the card application system , isn't consistent, isn't shared and isn't updated instantly. In addition, the coupling between the card management system and the card application system is tight.The middleware of the data transmission, developed by this article, can solve the above questions. The middleware can not only enhances the expansibility of The Campus One-Card-Through System,but also automatically and instantly update the related data of all the card application system in The Campus One-Card-Through System.It is based on Web Service and achieve safe, credibly data transmission between the card management system and the card application system. In the Campus One-Card-Through System,using the middleware of the data transmission,the function of the middleware of the data transmission provides the Web Service interface called by the card application system .
