Abstract

The reasonable organization of system data is the requisite and powerful technological means used to promote the efficiency of the system. Aimed at the data organization for the travel time acquisition system based on 3GS (GPS/GIS/GPRS), the article has designed a conceptual model of the system database according to the data requirement analysis, proposed a new hierarchical organization method of data based on the object-oriented theory, and designed a layered logical model of the dynamic information database of the system. The hierarchical data organization method can be used to provide technical support for improving the system efficiency and the timeliness of the acquired travel time data.
