Entreposage et exploitation de documents multidimensionnels évolutifs. Le cas des tableaux statistiques

One of the main advantages of document digitalisation is the improvement of processing and research. Structured documents contents can be stored in a database management system (DBMS) for efficient processing independently of the original format. Statistical tables, which are highly structured, multidimensional and evolving are such documents. Extracting high volume of statistical data and integrating them in a database need to be automated. Database exploitation must address the evolving characteristic of the information so that this task must be automated too. This paper deals with multidimensional modelling of any kind of statistical tables, presents a prototype allowing to extract data and to store them in the database, and put forward a help tool to interpret the changing data. MOTS-CLÉS : entrepôt de documents multidimensionnels, tableaux statistiques, base de données, outil d’extraction de données.
