Abstract
This paper discusses the design method to construct the geospatial database for the China - Kazakhstan tourism resources information system, especially focuses on the design of the relational database structure for transportation network analysis. By expressing the logical structure of graph theory as four relational database tables, i.e. junction table, edge table, junction-edge connectivity table, and turning table, this topological structure can effectively express urban roads and inter-city roads within a relatively larger area and build complicated road networks, and it also can be applied to the shortest path analysis on different spatial scales.
