This paper summarizes the design, development and testing work of Study Room Management System in Library of Wenzhou Medical College. Based on B/S architecture, using the existing campus smart card system and the technologies of Flash, ASP and database, the system realizes the functions such as distributing seats automatically, choosing and exchanging seats, seats reserving time over management and displaying the position and status of the seat in graphic animation. Further more, it resolves the low seat utilization problem resulting from the occupation of the seats in contemporary college library study rooms.
