| Abstract: | In this paper, a Business-Driven mechanism of Finding Land Use Change Information and its implementation method is studied, and a Technical Solution based on database trigger is proposed to capture the land use change data. This Solution includes the trigger automatic configuration and cache, transport and management of change data. Combining with the pilot application, we fully complete the technical solution. The pilot result shows that this research achievement can improve the efficiency of land use capture and carry out effective management and application. |
