Abstract: Dynamic target has a lot of characteristics such as spatiality, timeliness, multidimensionality, magnanimity, complexity and uncertainty, but the traditional DBMS can't provide an effective way for its position modeling, semantic expression and index In order to solve this problem, this paper presented a general framework to model, analyzed and managed the dynamic target spatio-temporal data by analyzing the dynamic target. This framework uses three-layer structure, insuring the system with high flexibility and expansibility. Finally, a prototype system based on the framework was given, and the main componented of platform were analyzad and expounded.

Key words: Spatio-temporal data, Dynamic objective, Space information system
