Abstract
With the development of computer technology, network technology, construction of a reliable, efficient online homework and question answering system to reduce workload of specialized course teachers, teachers and students work and study convenient, timely and properly deal with all kinds of problems existing in the students’ learning, to establish a good teaching, learning platform and communication platform is necessary between the students and the teacher, also can very good education as the traditional way of a favorable supplement.
The design of this paper is based on the B/S structure of the WEB “C++” online homework and question answering system, the system divides the teacher module and student module. The online homework and question answering system mainly realizes the functions: C + + program for the operation management (including homework arrangement, completed online, grading, management, etc.), simple exercise library management, online FAQ management, learning data management, including data upload and download. Detailed description of the database design, as well as the realization of the function of the system.
Key words: job and question answering system; B/S structure; database
