A dynamic data with amendments model is proposed here on the basis of the base state with amendments model. Combined with the double-database strategy which stores history data and current data respectively, the new model further becomes the double-database strategy dynamic data with amendments model. Employing this model to store and manage temporal data can effectively reduce the data redundancy and improve the efficiency of current data query.
