The Database System Design In Internet Query System Based On Location Service

Location-based services (LBS-Location Based Service) is now one of the valuable applications in the field of mobile communications business at this stage. With the continuous development and improvement of the network communication technology, mobile communications services to mobile operators have a lot of business opportunities, especially value-added location-based services business. Modern standard of living is already high, a variety of mobile communication devices are getting into people’s lives, and these communications equipment will be the best bearers of the future location of services. Relying on this, by means of location-based services anytime, anywhere wireless life is just around the corner. The number of mobile phone users in China, and are rapidly mcreasing in mobile phone users in china are potential customers of the future location service application, therefore, the location services industry in China will become the most momentum of development.This paper studies the location-based services, database query system. It first introduced the application status of the development of location-based services system, clarified the location service system structure, and described the key technologies used in this system. In-depth understanding of the basis of location-based services basics and key technology research, we design the overall architecture design of the location-based service system, including system architecture designing, using functional of GIS and database designing, this article focuses on database designing; this article database design using ER data model, using the SQLserver database system as a data storage center to Mapinfo9.5development platform to complete the design of the database query system, a simple implementation on this basis, the location inquiry service location query includes a location query and the surrounding query. In this paper, it will give some system instances. Summarizes this work in the paper, pointed out that there are advantages and disadvantages, and to improve their work in the future outlook.
