Abstract: Traditionally, data warehouses have been designed guided by an analysis of the underlying data sources. On the other hand, goal-oriented approaches build a goal decomposition structure which is further mapped to a data warehouse model. Goal-oriented approaches address the requirements of the decision makers. In this paper, we propose to build a goal decomposition structure for traditional data warehouses. As a result it can be assessed whether the existing data warehouse model satisfies the decision makers' requirements. The approach is bottom-up wherein the tasks are identified first and the path to the strategic goal is built later. The tasks themselves are identified using OLAP query recommendation technique.
