基于Oracle Spatial的北京城市空间要素数据库实现

Implementation of the Database Management System of Urban Space Elements in Beijing Based on Oracle Spatial

现阶段,城市研究中涉及的空间数据逐渐增多,如何将这些研究中用到的海量多源异构空间数据进行一体化管理,同时提高数据的安全性和加快数据的访问速度,是急需解决的问题。为此,重点探讨Oracle Spatial 11g空间数据建模的特点,并结合其能够将空间数据与属性数据一体化存储的特点,基于Oracle Spatial建立北京城市空间要素数据库,对已有的城市研究数据进行统一化管理,提高数据的使用效率。

With the increasing spatial data in urban study, an integrated management of the huge amount of the multi-source heterogeneous spatial data and the promotion of its security and access speed become urgent. This paper optimized Oracle Spatial characteristics of 11 g spatial data modeling, and with its capability to integrate the store of spatial data and attribute data, a proposal was made to build Beijing urban space elements database based on Oracle Spatial in order to realize a unified management of the existing urban research data and to improve data use efficiency.
