Abstract:
XML is commonly used to store data and to exchange it between a variety of systems. While centralized querying of XML data is increasingly well understood, the same is not true in a scenario where the data is spread across multiple nodes in a distributed system. Since the size of XML data collections are increasing along with the heavy workloads that need to be evaluated on top of these collections, scaling a centralized solution is becoming increasingly difficult. A common method for addressing this issue is to distribute the data and parallelize query execution. This is well understood in relational databases, but the issues are more complicated in the case of XML data due to the complexity of the data representation and the flexibility of the schema definition. In this talk, I will introduce our new project to systematically study distributed XML processing issues. The talk will focus on data fragmentation and localization issues.
This is joint work with Patrick Kling.
Bio: M. Tamer Özsu is Professor of Computer Science and University Research Chair at the University of Waterloo and Director of the David R. Cheriton School of Computer Science. Prior to his current position, he was with the Department of Computing Science of the University of Alberta between 1984 and 2000. Dr. Özsu's current research focuses on three areas: (a) Internet-scale data distribution, (b) multimedia data management, and (c) structured document management mainly within the context of XML query processing and optimization. Dr. Özsu is on the editorial boards of ACM Computing Surveys, Distributed and Parallel Databases, World Wide Web Journal, Information Technology and Management. He is the Co-Editor-in-Chief of the forthcoming Encyclopedia of Database Systems and serves on the editorial boards of two Springer book series: Web Information Systems Engineering and Internet Technologies, and Advanced Information & Knowledge Processing. He chaired ACM Special Interest Group on Management of Data (SIGMOD) between 2001 and 2005 and was a trustee of the VLDB Endowment between 1996 and 2002. He was the Coordinating Editor-in-Chief of The VLDB Journal between 2001 and 2005. He currently serves on ACM Publications Board.
