Nouha Arfaoui, Jalel Akaichi, Cité Bouchoucha · 2012
The Data Warehouse (DW) is considered as a repository that contains data collected from different sources. Its design is one of many issues treated in the literature. It is considered as the most important since it influences the quality of DW projects. Despite the number of works that have done, the design still suffers from many problems such as the lack of a consistent methodology that assists the user. In this work, we present a survey. It contains a presentation of the conceptual design models and the different logical schemas that exist.
