SQLTutor是自主开发的一套SQL查询语言智能学习系统，它利用在线实验组织教学，在实验平台上集成了资源学习、案例演示、在线讨论、综合测试等内容。SQLTutor最大的优势在于开放地允许学生对同一问题用不同的查询语句来实现，有利于提高学生的问题解决能力。论文剖析了SQLTutor实验平台的工作机制及特点，讨论了实验语句的语法错误和逻辑错误的诊断技术。实践证明，利用开放的在线实验技术有效地提高了学生的学习效果。

SQLTutor is an intelligent teaching system for Structured Query Language. Not only can it organize the teaching program through the online experiment, but it also integrates the learning resource, case demonstration, online discussion, and comprehensive test onto its experimental platform. Moreover, the greatest advantage of SQLTutor is that it can openly allow students to use different query languages for the same problem realization, which is very helpful to enhance the students＇ ability to solve problems. The thesis analyzed the mechanism and characteristics of the experimental platform and presented the diagnosis technique of syntax mistake and logic error as well. Practice has proved that the SQLTutor system, by using the opening online experimental technique, can effectively improve the students＇ academic performance.
