Abstract: The national geodesy data storage, management and application services develop rapidly recently with the development of the new geodetic technology system. This paper studied the content, characteristics and classification of modern geodetic data, and proposed a real time data storage, management method based on the database DBFS technology, as well as the modeling of all kinds of data entities (observation data class, result data class, summary data class and Auxiliary data Class) are analyzed and realized. To meet the requirements of modern geodetic data acquisition, storage and real-time service, database and management system was optimized, the composing structure and system function of geodetic database realized, and better meeting the requirements of modern geodetic data management and application.

Key words: modern geodesy, DBFS technology, database system, architecture design
