摘要:The Spatio-temporal object is a kind of complex temporal objects. Here, four basic constructors, i.e., tuple, set, list andtemporal, are introduced to construct an algebraic model of complex temporal objects. Transformations from varioustraditional temporal relational models to the temporal object model are illustrated. The study has shown that the algebraicmodel of complex temporal objects has more advantages over temporal relational models in complex structures andtemporal semantics modelling
