The Change-of-Feature Spatio-temporal Object Relational Model and Its implement

Now more and more application demand to spatio-temporal database is proposed and the spatio-temporal data model is the fundamental basic to spatial-temporal database. But till today the study on spatio-temporal data model still more concerned with the theory research. The article proposes a new model-the change-of-feature based spatio-temporal object relational data model by researching and analyzing the current spatio-temporal data models. The article mainly introduces its concept model, character and implementation, finally uses the software-Postgresql to test practicality. This article is an attempt to realize the Spatio-Temporal data model using in practice.
