Resumen
Document warehouses allow the storage of selected and filtered heterogeneous documents, as well as their exploitation through multidimensional analyses techniques. However, the content of documents is dynamic and changes over time. In practice, decisional analysts may be interested in various versions of documents. The document warehouse should store and manage these versions. This paper presents an extended generic model for document warehouses allowing the management of multiversion documents. In addition, it proposes a multidimensional analysis of the document versions.
