县级地名时空数据库的设计与实现

Design and implementation of spatio-temporal database for county-level toponym

地名是最常用的社会公共信息之一,本文顾及地名的时空特性,基于地名的变更,结合基态修正模型和序列快照模型理论思想,以关系数据库为实现平台,设计了县级地名时空数据库,解决了分类存储地名数据的数据库的臃肿问题。并以福鼎市地名变更为例,实现地名时空数据库,给出了新增地名、地名更新、地名注销和数据库查询等方面的实例分析。

Toponym is one of the most common social and public information. Considering the temporal and spatial characteristics, based on the changing of toponym, combining the theory idea of Base State with Amendments model and Sequent Snap Shots raodel, using the platform of the relational database, the paper designed a county-level toponym spatio-temporal database, which solved a bloated problem of the database with classification storage toponym data. Finally, taking the toponym changing of Fuding Cit- y as example, it realized the toponym spatio-temporal database, and then gave the instance analysis of adding toponym, changing toponym, toponym cancellation and database query, etc.
