RESUMO

This work aims at the development of Learning Objects Digital Libraries (LO-DLs), using Data Warehousing (DWing) and Data Mining (DMining) techniques. By using the Data Warehousing approach, we will be able to correlate the main steps of this technique, which area Extraction, Transformation, Loading and OLAP, with the main services of a Traditional Library which are Acquisition, Subject Classification, Cataloging, and Searching, so that they will work in an automatic way. Data Mining techniques are incorporated in some of these processes automating the process of the development of the library. Besides integrating multiple LOs sources, which are stored in diverse DBMSs (Data Base Management Systems) and catalogued in different metadata languages, this approach contributes to providing the user with a sophisticated query to the library that is more comprehensive than the usual author, subject or title options, since OLAP allows multidimensional access. Furthermore it also contributes to the improvement of the library, since OLAP and data mining techniques are used to analyze LOs data and the access to them. An automatic refresh of the library is made when users´ profile changes.
