Answering System Based On Php Online Research And Realization

The popularization of the Internet and fast development of Web technology have significant impact on traditional MISs. The net answer system is one of hot areas of computer applications, asking and answering questions between students and teachers are not restricted by the space-time in the network teaching, a teaching form being not face to face.It represents the characteristics of long-distance education,such as opening,interacting,self-determining and so on.In this paper,I have first given the system structure of distance education system based on Web,and then analyzed the shortage of C/S mode,the network structure and characters of B/S mode.The system is based on B/S model—a three-tier model of browsers,Web Server and Database Server.It is derived from traditional C/S model.The main work of this paper includes:1.Give the several basic technologies of Web database a completed review comparison and summarization.Detailed introduction and analysis about their advantages and disadvantages.Therefore,useful and practical computer structure was proposed for the project.2.OOAD technology was used to design the Web database system.IBM Rational Rose 2005 produce was used to analysis the use-cases.3. Introduced a system based on PHP net Answer system and structure of the basic functions and Implementation of the way of the net answer system based on PHP technology.MySQL is used as database development platform and it has features such as convenient use,good scalability and high level of integration with relative software.PHP technology is adopted to design user interface and it has features such as high portable feature,high efficiency of code execution and convenient connection database. It has realized the function of question,Answer,browsing,search,statistics and so on.We also has made the discussion to its key question:such as the natural language inquiry way,the user's page transmission,the picture uploade,the classified induction question and so on,and it has given the way that how to solve them.In the summary,I point out the problems still exist in the system and the farther work.
