| Abstract: | In recent years, how to use spatial database to store and manage spatial data has become a hot topic in the field of GIS. However, the study on spatial database structure design has been ignored relatively. Most investigations just emphasize the realization of special application of softwares which are relative to spatial database. Accordingly the author carried out a comprehensive and in depth discussion about the related questions in this article, including the difference between spatial database and general database, the key technology and frequently asked questions while building spatial database. In this article many important thoughts and rules for the different design stages are put forward and the importance of standardized design is also emphasized. In the structure realization stage, a detailed treatise about how to scheme out a perfect Geodatabase with CASE tools has been given. The facts proved the importance of UML and CASE tools in the design of spatial database. |
