空间数据库访问接口工具设计与实现

研究了空间数据库接口现状和空间数据库相关的理论体系结构,重点讨论了空间数据库的存储机制、索引方法、查询和接口设计标准等相关内容。在此基础上采用ADO数据库访问技术,以Access、SQL Server等商用关系数据库为数据库管理系统,设计与实现了一种空间数据库接口程序。采用VC++6.0高级语言设计和实现了数据库接口试验系统,并以几种流行的空间数据文件格式数据为例,实现了其在关系数据库中的存取、索引建立、属性数据与几何数据联合查询等接口功能。

Design and Realization of Spatial Database Accessing Interface Tool

Based on study of current situation of spatial database interface and correlative theory architecture of spatial database,the storage mechanism,spatial index,query,interface design standard of spatial database and related topics were emphasized discussed.Adopting ADO which is one of the database accessing methods,a spatial database interface program with relational database such as Access,SQL Server and etc.were designed and implemented.At last,a database interface testing system under VC++ environment were designed and implemented,and taking several data formats of pop spatial database as examples,the interface function such as the storage several data formats of pop spatial database as examples,the interface function such as the storage,index building and joint inquifing of attribute data and geometry data were implemented.
