Abstract (EN):
Monitoring the user behaviour of an information system (IS)
is a valuable way to assess its impact and to guide its
improvement. In the case of Web Based IS this is usually
done analyzing the Web server logs or clickstreams, a too
low-level approach with huge amounts of data. Dealing with
this calls for data warehouse techniques, which abstract the
clickstream to notions like session and navigation path and
combine them with information on the structure and meaning
of the IS and its users, leading to what is called a Data
Webhouse. The paper presents the dimensional modelling of
a data webhouse specifically designed to monitor Web-based
Higher Education IS and describes some aspects of its ETL
process instantiation in SIGARRA, the WBHEIS of the
University of Porto.
