Based on the field model, a uniform dynamic field model is proposed to support representing the characteristics of distribution continuity and time development of spatial phenomena. Through analytical expressions and arrays data structures, data types and operating functions of the new model are extended in an object-relational database to support uniform representation, management, access and spatio-temporal querying for continuous and discrete dynamic fields. Several examples are demonstrated to discuss the representing and querying ability of the new model and its database extension.
