Requirements Driven Data Warehouse Development

Data Warehouses are decisional information artifacts that are embedded in the organizations that create/maintain them. Therefore, Data Warehouse Requirements Engineering must start from goals and work its way to the decisional information needed to take decisions that fulfils these goals. We propose two associations, the goal-decision association and the decision-information association to represent this. These associations form part of a larger model called the goal decisional information (GDI) model.
