Towards A Generic Conceptual Model for Data Warehouses

Abstract

During the last few years, developers had proposed various approaches to the conceptual design of Data Warehouse (DW). Due to the variation and differences between these proposed approaches, this paper will first show the multidimensional modeling properties that are required to be supported in the conceptual model of DW then it will compare and evaluate the proposed conceptual modeling approaches. After Evaluation, the model that was categorized to be the best model for DW conceptual Design will be taken through this paper for further extensions to address all multidimensional properties that it had missed and also extend it to support the conceptual design of Temporal DW.
