电子商务教学与实验网络平台的构建

Construction of Electronic Commerce Teaching and Experiment Network Platform

电子商务教学与实验网络平台由虚拟个人学习室、教室、电子商务实验室、考场、讨论室、管理室组成。定义网络学习平台的组成单元、功能结构和基本模块及模块公共接口后,用模块封装并存于模块库。在低层框架上构建应用逻辑层,并用元数据文件描述模块功能。用户只要给出接口和功能描述,应用逻辑将在模块库中自动选择适合功能的模块并通过具体机制实现其功能。

Electronic commerce teaching and experiment network is composed of virtual individual study room, classroom, electronic commerce laboratory, examination room, l discussion room and management room. After the defined compositive unit, function construction and basic module and module public interface of network teaching network, modules were encapsulated and stocked in the module database. Application logic layer was established in lower layer frame, function module was described with metadata file. As long as users give the interface and function description application logic will automatically choose adaptive modules in the module database to complete their function by concrete mechanism.
