This paper deals with temporal and archive object-oriented data warehousemodelling and querying. In a first step, we define a data model describingwarehouses as central repositories of complex and temporal data extracted fromone information source. The model is based on the concepts of warehouse objectand environment. A warehouse object is composed of one current state, severalpast states (modelling value changes) and several archive states (summarisingsome value changes). An environment defines temporal parts in a warehouseschema according to a relevant granularity (attribute, class or graph). In asecond step, we provide a query algebra dedicated to data warehouses. Thisalgebra, which is based on common object algebras, integrates temporaloperators and operators for querying object states. An other importantcontribution concerns dedicated operators allowing users to transform warehouseobjects in temporal series as well as operators facilitating analyticaltreatments.
