摘要
地理信息系统(G IS)由多个部分组成,但是在多个部分中数据库是基础。数据库是一个庞大的工程,它由人力、物力和时间资源高额投入,但需要很长时间才能见效的系统。在整个G IS建设中,数据库占了很大的一部分。虽然现在的数据库已经是一门成熟的技术,但是在应用的过程中仍存在很多问题,值得关注和重视。
Geographic information system （ GIS） includes aplura lity of parts, but database is the foundation of multiple parts. The database is a huge project, which consists of labor power, material resources and time resources, but it should take along time to bear fruit. Database accounts for a large part of GIS construction. Although the database has already been a mature technology, there are still many problems in the application process, which should attach concern and attention on them.
