On behalf of the Organizing Committee, we would like to welcome you to the proceedings of the 10th International Conference on Database Systems for - vanced Applications (DASFAA 2005). This conference provides an international forumfortechnicaldiscussionamongresearchers, developersandusersofdatabase systems from academia, business and industry. DASFAA focuses on research in databasetheory, andthedevelopmentandapplicationsofadvancedDBMSte- nologies. This was the second time that this conference has been held in China, the?rst time was in Hong Kong in 2001. China is the third largest nation in terms of size, with the largest population in the world. The capital, Beijing, is a great metropolis, famous in Asia and throughout the world. We therefore were most privileged to host this conference in this renowned location. This volume contains papers selected for presentation and includes the three keynote talks, by Dr. Philip Yu, Prof. Elisa Bertino and Prof. Deyi Li. The conference also featured two tutorials: (1) Data Mining Techniques for MicroarrayDatasets, byLeiLiu, JiongYangandAnthonyTung, and(2)Pattern Management: Models, Languages, andArchitecturalIssues, byBarbaraCatania.
