The Design And Implementation Of The Online Question Answering System For School Curriculum Based On JFinal

With the rapid development of Internet, the information is exploding,which is filled with the large amounts of spam. Search engines have been unable to meet the demand of users, but knowledge sharing platform can aggregate information, accurately meet user demand,provide users with high quality and preciseness of the data, save time for users to find information, solve user problems fast accurately. This subject mainly research on online question answering system for school curriculum, to help the students of CS or IT to deal with the difficulties encountered in the study, to provide a platform for the exchange between teachers and students, to enhance the students’ interest in learning.First of all, this paper analyzes the background and significance of online question- answering system for school curriculum and describes the main research content and structure. And it describes the domestic and foreign related work of online question-answering system for school curriculum. In order to research more deeply and combine the feature of the schools, we will design and implement professional online question-answering system. Then, it overviews online question-answering system for school curriculum and the related technology of development, and compares related technical and chooses related technologies which the system need. At the same time, based on certain design objectives and principles of this system, it introduces system demand analysis focus on two points that the overall system functions and business processes. According to original research and analysis, the factors that students do not take full advantage of their leisure time will have a great influence on communication between teachers and students, thus it will affect academic performance. In online question-answering system for school curriculum, students can ask teachers for help when he or she is in trouble in study.

Thus, it will enrich the teaching methods, improve the quality of education and the interest of students in learning, and have a significant effect on actual teaching work.What’s more, we use My SQL database, JAVA language and JFinal technology, then achieves overall system design, preliminary design,database design and REST interface design, to complete the design of the entire system. And it implements online question-answering system for school curriculum through seven modules, which are the system home page, user login and registration module, materials sharing module, social question-answering module, station communication module, a personal information management module and background management module. The system was tested and the results was shown that each of function modules can be used normally. Finally, this paper summarizes the achievements of this research, and also points out shortcomings and further improvement.
