基于Geodatabase的数字校园空间数据库的设计与实现

摘要

The organization of the spatial data in the database about digital campus is directly related to the management and query performance of the spatial database system.And the space-based Geodatabase has irreplaceable advantages on variety of systems.The article first introduces the concept and type of the Geodatabase,and analyzes its characteristics.Taking Nanjing Forestry University as an example,it analyzes and successfully designs the background spatial database using the Geodatabase Data Model for 3D campus Geographic Information System,and demonstrates the advantages of the design of spatial database using this method in terms of performance,providing the building of the Digital Campus with technical support.%数字校园中空间数据在数据库中的组织形式,直接关系到整个空间地理数据库系统的管理和查询性能,而基于Geodatabase的空间数据库对各种系统有着不可替代的优势。文章首先介绍了Geodatabase地理数据库的概念与类别并分析其特点,以南林大校园为例,分析并运用Geodatabase数据模型成功设计了3维校园地理信息系统的后台空间数据库,论证了采用这种空间数据库的设计方法在性能方面的优势,为建设数字化校园提供了技术支撑。
