UREM-A UML-based Requirement Engineering Model for Data Warehouse

Data Warehouse is a collection of data collected not only for storage purposes but for business analysis as well. For this the data that is to be stored must conform to some standards. As this data is to be used for business intelligence, it makes the design of data warehouse a difficult task. For any system, gathering the requirements forms the basis for design. The quality of the data warehouse depends on the quality of the requirements gathered. Hence a good amount of time and resources should be devoted to requirements engineering. For this various techniques have been proposed such as GORE, AORE, MORE, SCENARIO based etc. each handling requirements in a different way. In this paper we have combined scenario based approach and UML (Unified Modeling Language), and proposed a model for requirement engineering of a data warehouse which will help in its design process.
