Abstract: Data warehouse (DW) quality depends on the quality of its requirements, conceptual, logical and physical models. Some of the authors have proposed guidelines and metrics to assure the quality of conceptual, logical and physical models for DWs. However, there is a lack of guidelines for the requirements analyst to obtain a quality requirements model for DW. In this paper, we propose a quality-oriented requirements engineering approach for DW, where: 1) existing agent-goal-decision-information (AGDI) model is extended with the notion of perspective to capture intentions of the agents; 2) based on proposed model of (1), DW requirements are captured through various modelling activities namely; organisation modelling, decision modelling and information modelling; 3) in order to assure quality of requirements model, various guidelines are proposed that must be followed by the analyst while performing various requirements modelling activities of (2). The proposed approach is illustrated for capturing DW requirements through a running example of a public sector banking organisation.
