| At present,many colleges and universities are mostly using the traditional manual way to check on work attendance.This way has its problems such as the error-prone,high cost,opaque and it can not solve the problem about absent.With the coming of"the Internet Age",the scientific and advanced solutions will be cried for--"The Mobile Attendance System",it indicates that problems such as the real-time,accuracy,region across and management problems will be implemented.Based on currently popular J2ME and J2EE technology,this article make a detailed exposition of the difficult problems of the wireless terminal the MIDlet application development,server-side application development and wireless terminal server information exchange.Eventually,a set of University Mobile Work Attendance application platform used in mobile phones and other mobile environments is developed.The main system functions include System Management,Attendance Records Management,staff mobile attendance and Employee Information Management..The overall architecture of the application of platform is divided into three layers by using S2SH,presentation layer,business logic,and data persistence layer.The effective separation of the system of the multilayer structure data is achieved,the degree of coupling between the modules of the various levels is greatly reduced,and system reusability is fundamentally improved.The platform adopt open modular design,this could benefit system program upgrade.Under the premise of not expanding the size of the original system,users could increase system application modules according to their own needs,in order to achieve the expansion and reorganization of the system.In summary,the system has good scalability and compatibility,and could design and develop a safe and stable University Mobile Work Attendance program by combining J2ME with J2EE.Finally,after a rigorous system running test,the results show that system is running well,and the desired development target is achieved. |
