A Hybrid Approach for Data Mart Schema Design from NL-OLAP Requirements

摘要

OLAP systems remain difficult to develop for two primary reasons. The first reason is that the REQ analysis step is typically overlooked [1]. The second reason is that, even when attention is accorded to this step, REQ are described from a too technical perspective for decision makers to understand and validate [2]. However, the lack of user involvement in the specification can easily lead to the failure of the project.
