基于Oracle Spatial的税收征管空间数据库的设计与实现

传统税收征管信息系统普遍存在空间数据利用率低、空间数据与属性数据单独存储、空间数据存储和访问的效率较低等问题。采用Oracle Spatial可以有效地组织空间数据和属性数据,并对两者进行统一管理,有效地提高了空间数据的存储和查询效率,并为税收征管WebGIS系统的建立奠定了基础。本文介绍了Oracle Spatial的运行机制与原理,详细阐述了基于Oracle Spatial的税收空间数据库(TAXSDB)的设计和实现过程,并提出了TAXSDB的优化策略。

The Design and Implementation of the Tax Administration Spatial Database Based on Oracle Spatial

In the traditional tax administration information system, there are some problems in common. Such as, the low utilization of the spatial data, the storage separation for the spatial data and the attribute data, and the low efficiency in the storage and access of the spatial data, etc. The Oracle Spatial can be used effectively to organize the spatial data and the attribute data, and perform the unif ied management for the two above. It can improve the efficiency of the storage and query of the spatial data, and will lay the foundation for the tax administration webgis system. In this paper, the principle and mechanism of the Oracle Spatial are introduced, the processes of the design and implementation for the tax administration spatial database (TAXSDB) are described in detail, and the optimization strategy for the TAXSDB are proposed.
