Abstract
銆?/p>
Traditional spatio-temporal data model based on relational database
锛?/p>
which will
result in hard to convert problem domain model to relational model
锛?/p>
complicated query and low
expansibility. In view of this
锛?/p>
we propose the spatio-temporal data model based on graph database.
The data model integrated TGIS鈥檚 three key elements
锛?/p>
space
锛?/p>
time and attributes
锛?/p>
expressed
spatio-temporal characteristics of TGIS explicitly.
