【摘要】 本文针对现有地下水空间数据库存在的一些不足之处,提出了基于关系数据库存储的地下水空间信息的数据模型,并利用关系数据库系统实现了存储地下水空间数据。文中介绍了地下水空间数据结构并根据地下水特点给出空间数据的存储表的逻辑结构,设计并实现了新型地下水空间数据库。新型地下水空间数据库可以将地下水空间图形和属性统一存储于关系数据库中,改善了传统地下水空间数据库采用文件———数据库混合存储所带来的诸多不便,在实际得到应用,效果良好。更多还原

【Abstract】 A data model of groundwater spatial information about relational database is presented in order to solve several existing problems of groundwater database and to store groundwater spatial data, based on system of relational database. We introduce structure of groundwater spatial data and picture logical structure of storage table, according to feature of groundwater. At last, a new design of groundwater spatial database is implemented. This newstyle groundwater spatial database will help groundwater spatial pictures and its characters to store uniformly in the relational database, which overcomes many difficult brought by mixed storage (filedatabase) in traditional groundwater spatial database.更多还原
