Abstract:
Optimum design of geographic information system for highway natural regionalization is developed in order to improve the accuracy and efficiency of highway natural regionalizing. By choosing the recovery model of “simple” and “bulk-logged”, using the API function, the speed of data loading optimized and bulk data copying is significantly improved. By introducing DECODE function to optimize the SQL statement, the temporary table is established to optimize the query cache. It is found that these optimization methods can reduce the system response time and improve I/O and CPU speed. 7 figs, 6 refs.
