| Abstract: | According to the characteristics of management object persistence and complex data structure of South-to-North Water Diversion Project in Beijing, the article uses the object-oriented thinking, puts forward the overall design, the composition and contents of the basic spatial database of South-to-North Water Diversion Project management of Beijing, expounds the key process of the database design focus from the management object classification, object code and object spatial relationships etc, and uses UML modeling language for database modeling. It provides data support for the project management, and provides the basis for future businesss application. |
