Data warehousing involves complex processes that transform source data through several stages to deliver suitable information ready to be analyzed. Though many techniques for visual modeling of data warehouses from the static point of view have been devised, only few attempts have been made to model the data flows involved in a data warehousing process. Besides, each attempt was mainly aimed at a specific application, such as ETL, OLAP, what-if analysis, data mining. Data flows are typically very complex in this domain; for this reason, the authors argue, designers would greatly benefit from a technique for uniformly modeling data warehousing flows for all applications.
