Résumé
Recent research works propose to use the Unified Modeling Language (UML) to design datawarehouses. First, the paper overviews these recent UML-based techniques. We show that UML can help system designers to build a data warehouse model. This type of model aims to describe the different analysis dimensions of the data. Second, we will also present different UML-based tools used during a project of agricultural data warehouse. The paper will introduce this data warehouse developed in France. Its goal is to allow analyzing spatially the use of pesticide in agriculture.
