ABSTRACT

Now in the rapid development of computer networks, network became to learn

knowledge and fast access, publications and important way of passing information, networking in the political, economic, and cultural aspects of life play an extremely important role. Excellent courses website is concluded in the course of daily teaching teachers, accumulation of teaching content, teaching methods, teaching materials and a series of teaching materials, platform presented through the network, to allow students to better learning through the Internet. And online answering questions on the Web site to resolve problems encountered in student learning, further enhance the students ' knowledge, thereby enhancing the quality of education in schools.

This paper is devoted to the UI through the use of Flex technology, Java and MySQL database management software to create a top-quality course website. Dynamic Web pages Web sites by means of information display, uses the MVC pattern, and DAO for data access. Enables the user to online access to information on courses, download if you want to know a curriculum of courseware and online features such as question answering.

Keywords: quality course website Flex MVC DAO MySQL.
