Call For PapersNew Book on Data Warehouse |
I received my Ph.D. degree from the Blaise Pascal University Clermont Ferrand - France in Database Systems area
(advisor Prof. Michel Schneider) in December 2000. My Ph.D. thesis was on "logical and physical design of a data
warehouse". I got my Masters degree in Computer Science in 1994 from Paul Sabatier University, Toulouse - France.
I received my Engineering Degree in Computer Science from Djilali Liabès - Algeria in 1992.
Before joining Poitiers University - France, in September 2002, I have been a visiting researcher at Hong Kong
University of Science and Technology from 1997 to 1999, where I worked with Dr. Kamal Karlapalem on distributed database
design and data warehousing. I have also been a visiting researcher at Purdue University
USA during summer 2001, where I worked with Prof. Bharat K Bhargava.
