地下管网时空数据库设计与应用

Design and Application of Underground Pipeline Spatio-temporal Database

探讨了三维管网信息系统后台的时空数据库设计原理,在保留现有时空数据库设计大部分特性的基础上,内部采用全关系化的设计模式,协同管理空间数据和非空间的三维模型数据,应用到数字城市的三维管网系统建设项目中,取得了良好的效果。

Based on those achievements and maintaining most characteristics of the existing spatio-temporal database,we discussed the design principle of 3D pipeline system spatio-temporal database in this paper.Meanwhile,taking account of complying with the database constraint specification,we minimized data redundancy and combined database query with update efficiency.Then,we used the design patterns of whole relationship in the internal manage,and achieved the uniform management of spatial data and non-spatial data.Finally,we applied the 3D pipe network system to the Digital City construction project.
