【Abstract】 With the rapid development of middleware and the Web,the application system of three-tier database is increasingly popular. Due to frequent unexpected visitors to the course-selection system for colleges,traditional two-tier structure may impose an overload upon the database server,and even lead to the crash of system. This paper is intended to analyze and research the characteristics of course-selection system with a three-tier basis,and designs this system according to software engineering methods.更多还原
