互动教学系统的设计与开发研究

Design and Recreation of the Interactive Teaching System

随着Internet的蓬勃发展,网上教学模式越来越得到人们的认可,互动教学系统作为教学模式的一种形式正以其高效、低成本的优势,逐步成为一种新的教学理念。由于教学系统的用户量大,在这种的环境下更注重的是系统的稳定性、可用性和高性能以及便于操作性。针对广东石油化工学院教学与工作的需要,设计并实现了一个多元化互动功能的教学系统。系统使用缓存技术和高效的算法,提高系统的性能,利用iBatis本身的缓存机制对频繁访问的页面进行合理的数据缓存;在数据层使用iBatis进行持久化,以面向对象的设计开发思想映射数据库。

With the rapid development of the Internet, online teaching is increasingly being recognized by the public. The interactive learning system, as a teaching model with high efficiency and low cost, is gradually becoming a new teaching idea. Because of its large number of the users, the teaching system should pay more attention to its stability, availability, high performance and feasibility. Out of the need of the teaching and work of Guangdong University of Petrochemical Technology, this thesis designs and accomplishes a di- versified interactive teaching system. The system uses caching technology and high efficient algorithm to improve its performance, the caching mechanism of iBatis for reasonable data cache of frequently accessed pages, iBatis to keep the persistence in the data tier, and＇ develops the thought mapping database by means of object - oriented design.
