A Hierarchy-Driven Compression Technique for Advanced OLAP Visualization of Multidimensional Data Cua the so-called OLAP dimension flattening process. A wide set of experimental results conducted on several kind of synthetic two-dimensional OLAP views clearly confirm the effectiveness and the efficiency of our technique, also in comparison with state-of-the-art proposals.

A Multiversion-Based Multidimensional Modele approach consists in storing star versions according to relevant structure changes whereas data changes are recorded through dimension instances and fact instances in a star version. The model is able to integrate mapping functions to populate multiversion-based multidimensional databases.

Warehousing Dynamic XML Documents be able to answer various user queries about its content or about the history of the warehoused documents. In this paper, we propose a methodology for warehousing dynamic XML documents, which allows a low degree of redundancy of the warehoused data, while preserving critical information.

However, these approaches often fail in providing mechanisms to univocally and automatically derive a logical representation of the MD conceptual model. To overcome this limitation, we present an approach to align the MD modeling of the DW repository with the Model Driven
