开放式MCAI平台的研究与实现

Research and Realization of Opening MCAI Platform

针对现在MCAI(多媒体计算机辅助教学)的不足,研究并开发了一个开放式MCAI平台.该平台使用数据库对媒体文件进行管理,使用ADO和OLEDBProvider连接数据库,采用TreeView控件提取数据库信息自动形成目录结构并实现平台的导航功能,用户可改变数据表结构以满足特殊要求.开发的平台界面友好,功能强,能够演示多种媒体文件,容易实现演示内容的自由切换.本文介绍的方法已经应用于实际项目的开发,效果很好.

An opening MCAI(Multimedia Computer Aided Instruction) platform was studied and developed based on deficiencies of current MCAI in this paper. In the platform, database is used to manage media files, ADO and OLE DB Provider are used to connect database, TreeView component is used to form hiberarchy automatically with information from database and realize the navigation of playing, users can change table structure to meet special requirements. The developed platform has friendly interface, good functions, capability of playing kinds of media files and easiness to switch contents quickly. The introduced method has been applied to two systems and brings effect beyond compare.
