| With the development of network education, network teaching playsmore important role in modem teaching. Network teaching requires a lot ofnetwork courseware. It needs courseware authoring tool to make networkcourseware. Because most system do not take into consideration the features ofthe courseware itself and some special requirements in authoring, it isinevitable to produce such questions in deployment, maintenance, updatingand coordination. The upgrade and development of the system is not very easyeven if the system itself.In this paper, we shall propose a designing thought and a designscheme, study the usual main technology of J2EE-based databasedevelopment and develop a wed-based support system of instruction whichhaving some value, and advise some task for next study.First, general analysis of the system is made in this paper, then the designobjective and functional model are given. Based on the characteristics ofsystem function. The system adoptes B/S structure model, regards wellexpansibility, according the method of module. All system is composed of threemodule: material maintenance, courseware maintenance and templetmaintenance. The development based on J2EE which has the specialities oforient object and easy expansibility and MYSQL. In this paper, we maindisccused the speciality and application of pacing technology, include theresearch of J2EE structures, the realizing means of different levels of J2EEWeb system and the reasonable organization of database logical structure andso on.The utility provides an platform where you can make, edit, release andmanage network courseware, you can make network courseware that arecharacteristic and communicative, that can fit with the authors'style andspecialties, that can accord with the educational technology rules. |
