Analysis And Design Of Medium Occupation Schools Network CAI System

In recent years, with the rapid development of Internet and video teaching, research and development of network CAI platform becomes more and more important. This paper introduces the network CAI platform features and the development of technology, there are many universities through CERNET connected with Internet, using Internet this emerging media to provide a group learning environment, will be available for all users to provide learning opportunities. Medium occupation school students has its particularity and teaching has its uniqueness, therefore, in medium occupation schools development and development network CAI platform will become more and more important. Network CAI platform for teaching and a single class each has its own features, but in the former than in the latter has more superiority.This platform is designed to help" computer foundation" the curriculum teaching, since it is to learn computer, so the network multimedia courseware made form, it will be better for students in computer learning interest, teaching content as video, sound, graphics rendering, and set up the course content discussion area, to be able to meet the curriculum teaching, self-learning, review and other requirements. Make a variety of sensory participation awareness activities, enable the students to grasp the knowledge, improve the quality of teaching.Taking the medium occupation school network CAI platform as the research object, in business on the basis of demand, the main business needs for the needs analysis, and gives the design scheme of project construction. This paper focuses on the following two aspects of the work carried out a detailed description of:1 for the business departments of the business needs, using UML and object oriented analysis method has carried on the detailed demand analysis, formed a relatively complete business process module;2 according to the needs of the business and the business requirements analysis, in the current technological development of fully understanding and on the basis of the analysis, put forward medium occupation schools network CAI platform system software structure and functions of the system design.
