However, in China, there is still a gap between the level of development of tourism and foreign work. Therefore, the study on the development of the work of tourism in China, analyzed the existing problems, has the important countermeasures are put forward to promote the tourism development of China work. The tourism information system, mainly uses the backstage management, design front display the remended way, through the back page for tourist route information, tourist information, Turisthotellet information, increase, delete, modify the tourism image information, query, and display remended in the front page, the users are most concerned about, the tourism information interest through the system display. After the use of the remended method, the tourism information system bees more intelligent, personalized, automation, one of the main goals of the tourism information system design. A key point of this system, which is also a difficult problem, is the large amount of data query. In a system, the query is essential for the function, and the query design directly determines the performance of the system. This system uses two ways to solve this problem. Firstly: optimization in the HQL statement,avoiding full table scans and multitable unioninquiry, this can increase the speed of database query. Secondly, the data caching mechanism of Hibernate is used to keep the data, and save a lot of query time. This can rapidly improve the query speed.
