An important use of data warehouses is to provide historical information by temporal views. Because it makes temporal extension to traditional relation data model, the materialized temporal views may be needed updated not only when base relations change, but also as time advances. So presently the research results for the non-temporal views are not applicable for the temporal views, and also the existed temporal view maintaining techniques are not appropriate for the data warehouses. Based on a historical relational model,according to the pure deletion and pure insertion concept,the change propagation are presented in this paper computation in relational algebra format for the five prve primitive historical relational operators.The incremental computaion of temporal views defined by the five operators can be obtained bu iterative method.At the same time,the pure insertion and the pure deletion con caaepted by this paper can be used in the temporal view maintence under other historical relational model.
