WWW-based distance learning network approach is the main long-distance education model. It provides a series of teaching aids the function of networks is the future of teaching in one of the main direction of development. However, distance education at this stage there is still a great shortage, but also keep waiting for the perfect! Online Q & A system is a very important part of them, it can take on the task of teaching as part of the network to make up for the students in the exchange of e-learning deficiencies. Online Q & A system to resolve the network teaching this form of non-face-to-face teaching students with difficulties in communication between teachers, students and teachers to promote the adoption of a network of learning face-to-face exchanges, and further improve the system of modern distance education. This article on the WWW-based form of Q & A system and method are discussed, and gives practical solutions. Author background for the development of practical applications, the use of software engineering principles and development methods, the use of the current mainstream web development technologies, combined with ASP and ACCESS database technology, designed and developed based on B / S mode answering system network. First of all, the development system needs analysis, the system functional requirements, data flow diagram and data dictionary. Followed by a summary of the system design and detailed design, design in a summary of the main functional modules to the system, broken down into to the system administrator control module, teachers and students control module control module three modules, which include administrative privileges new teachers and new students to register for the new administrator of the registration and approval of the experimental subject; authority, including teachers and management, as well as answer frequently asked questions, such as publishing and upload resources, students discuss the results of the review, answered questions of students; the issue of student rights, including release to eva luate the answers to your questions, upload relevant information and questions to teachers. Also outline the design of the overall structure of the system design, system design, data structure. The detailed design of the main system database, including access to the realization of the main functions of the concrete realization of modular, modules, etc. to achieve the key code. Finally, system functional testing, and test results are analyzed, in concluding, based on the analysis, pointing out that the system deficiencies and areas for improvement, the development of similar systems for future reference and help. The system user-friendly, easy to operate, able to basically meet the requirements of non-real-time Q & A.
