Dimensional fact model

The dimensional fact model (DFM) is an ad hoc and graphical formalism specifically devised to support the conceptual modeling phase in a DW project. DFM is extremely intuitive and can be used by analysts and non-technical users as well. A short-term working is sufficient to realize a clear and exhaustive representation of multidimensional concepts (e.g., attributes, measures and hierarchies). It can be used from the initial DW life-cycle steps, to rapidly devise a conceptual model to share with customers. DW design and development require ad hoc methodologies and an appropriate life-cycle.
