Abstract
Since data warehouse projects are large and complex, this chapter proposes an agile technique for data warehouse development. The notion of a data warehouse user story is developed and its difference with user stories of Scrum is brought out. A model-driven approach is presented using which it is possible to build data warehouse user stories. In this model, a decision-making application is seen at three levels. Agility involves obtaining a vertical slice across these levels and thereby defining a requirements granule. A granule is implemented as a data warehouse fragment. The issue of consolidating data warehouse fragments is considered thereafter and an approach to consolidation is formulated. It is proposed that consolidation of requirements granules should be done and therefore, the consolidation process is a part of the requirements engineering process. The chapter ends with a description of the tool support that is provided.
