摘要
目前在空间数据库更新方面虽取得了不少科研成果，但在诸如线状要素更新方面涉及甚少。鉴于此，以道路线状要素为实例，以路段为对象建立时空数据模型，并利用Oracle Spatial中的SDO（Spatial Data Object）对象～关系模型对增量信息进行组织与存取，最后通过试验实现了各种查询等功能。
At present spatial database updating has made some scientific research achievements, however it involves little on incremental updating of the linear features. So this paper takes the road-linear features as an example, and organizes and accesses the incremental updating using oracle spatial SDO （Spatial Data Object） object-relational model, with the spatio-temporal data model of road sections. Finally all inquiry functions are realized by means of experiments.
