RESEARCH AND APPLIED INTERESTS




On-Line Analytical Processing, Decision Support, Data Warehousing, Data Streams
Develop tools and algorithms to express easily and evaluate efficiently complex data
analysis reports. Current work involves large telecom, internet and business data sets.
Data Mining, Knowledge Discovery in Databases (KDD)
Using and generalizing previous tools and algorithms to discover “interesting” patterns in
large data sets (user-guided data mining).
Data Modeling
Multi-dimensional conceptual models, algebraic forms and languages for complex
decision support queries; object-oriented and attribute-oriented models; schema evolution.
E-Commerce
Research on integrating XML and database systems and the issues resulting from this
integration, such as performance, query languages, modeling, etc.
