Abstract
Requirement analysis approaches for data warehouse (DW) systems are only focused on information needs of decision makers, without considering other kind of requirement such as security or performance. However, modeling these issues in the early stages of the development is a cornerstone for building a DW that satisfies user expectations. In this paper, we define the two kinds of requirements for DWing as information and quality-of-service requirements. These requirements are defined within the MDA (Model Driven Architecture) framework, which allows their traceability towards the subsequent conceptual and logical design phases. It is worth mentioning that this paper focuses on proposing a requirement model for security (as a concrete kind of quality-of-service requirement), and a three-step process for modeling together information and security requirements.
