With the continuous development of computer technology, online distance education are more widely used, and online education and online examination is one of the applications. "Web-based distance learning system" is based on the B / S development of the typical management information system, it easy to use, simple operation, a wide range of applications.
"Web-based distance learning system," including online education and on-line examination of two subsystems, which include online teaching subsystem module students and teachers. Students can self-teaching in the Notice here for news operations available to teachers correcting in the room by answering questions; can chat with teachers and students to discuss the issue.
