The online bookstore, people can remain within doors will choose the books. Online bookstore is based on the actual demand, dynamic webpage technology development and application. The system is mainly a series of operation of commodity; and has the advantages of occupying less system resources, a large amount of information, and it can overcome the traditional book sales in the region, advertising, human resources lack of restrictions, can be well adapted to the needs of online sales. The main function modules of the design include: trading system by using 4 layer structure, mainly including: the presentation layer, control layer, business layer, persistence layer. Presentation layer: mainly responsible for user interaction and result display. The main access control
