A WAREHOUSING APPROACH OF SEMISTRUCTURED DATA

Multidimensional Analysis or On-Line Analytical Processing (OLAP) has generally used for the analysis of structured data, in the context of data warehouses. However, these techniques are not appropriate to manage or analyze semi-structured data, as XML (eXtensible Mark-up Language) documents. In this paper, we propose a meta-model of heterogeneous semi-structure data (Structure and Content) and a multidimensional model based on galaxy model in order to analyze the content of this data type according to several perspectives.
