Application And Research Of Special Push Mail System

The enterprise information system is limited in the wired LAN, so it is a matter to increase the mobility of information, which is become an important factor to improve the office efficiency and enhance the competitive power in the enterprise.The special PushMail system is researched and realized according to existing PushMail system,which combines the enterprise information system with PushMail service. The enterprise user gain the recent information by mobile terminal through this service.The fast and convenient information service for the user is provided by the PushMail service, which meets the need of business in anywhere and anytime, gets rid of wired limitation and improves efficiency.After analyzing and summarizing of WAP Push technology in the PushMail service ,firstly, several kinds of applications about PushMail technology and the manners to realize the PushMail service are contrasted in the domestic and foreign nowadays,The realizing manner for meeting the special PushMail system is put forward. The PushMail system model is built according to user's characteristic and the demand of the Special PushMail service.The model of the Special PushMail system is analyzed and expounded very particularly in accordance with the structure of wireless network and the characteristic of enterprise information system.The software architecture of server-side and terminal are designed.The database is designed as well.The business of customization,the business of cancellation and the operation process are designed. Secondly,the server of PushMail system is realized emphatically to realize the access of enterprise information,the information format conversion and the information pushing based on the J2EE.The database for Special PushMail system is realized, which based on SQL Server 2000 database as the background data management system of PushMail system. The software of analog terminal for receiving and displaying mail is realized based on J2ME.Several key technologies are expound in the designing and realizing process. Finally, the performance of the srever and the function of system are tested in this paper.
