With peopleÂs living standard unceasingly improving, the travel industry develops fast. However, the information level of the travel industry is relatively low, the management is backward, and the industry foundation is weak, which causes the low-level competition of travel companies. Therefore, the tourism information service system is designed, in which visitors can easily search for scenic spot information, book travel agencies and make the tourist routes. This study first discusses on the necessity of the construction of tourism information service system, and then introduces the related technologies in detail which are needed to build the system, such as J2EE technology, Java development language and SQL Server 2005 technology, etc. Then it specifies the construction of the tourism information service system which includes the business requirements of tourism information service, the goal of tourism information service system, functional and nonfunctional requirements, performance requirements and running environment requirements. Finally it describes the architectural design of the tourist information service system which has a certain applied and extensible value.
