Data management has evolved significantly over the last decade. A traditional database managed well defined, structured data, answered precise queries, and stored the data in trustworthy settings. Recent applications have expanded the scope of the data managed to include unstructured and semi-structured data as well as non-persistent data such as data streams. The types of queries expected are diverse, imprecise and including on-line analytical processing and ranking queries. Even the data is often stored in non-trusted third parties and yet these third parties are expected to manage the data and answer queries. Many of these innovative and challenging settings form the basis of the research projects we are exploring at UCSB. In this talk I will discuss recent results related to the execution of privacy preserving operations, the efficient execution of novel skyline operations, and detecting fraud in advertisement click streams.
Amr El Abbadi received his Ph.D.in Computer Science from Cornell University. In August 1987 he joined the Department of Computer Science at the University of California, Santa Barbara, where he is currently a Professor. In 1990 he was a visiting professor at the University of Campinas in Brazil, in 1994 a visiting scientist at IBM Almaden Research Center, in August 1998 a visiting lecturer at the Swedish Institute of Computer Science in Stockholm, Sweden and in July 1999 a visiting researcher at IRISA at the University of Rennes in France. He has served as area editor for Information Systems: An International Journal, an editor of Information Processing Letters (IPL) and Associate editor of the Bulleten of the Technical Committee on Data Engineering. He was Vice Chair of the 1999 International Conference on Distributed Computing Systems, Vice Chair for the International Conference on Data Engineering 2002, group leader for the International Conference on Management of Data (SIGMOD) 2005, and the Americas Program Chair for the 2000 International Conference on Very Large Data Bases (VLDB). Currently, he is a board member of the VLDB Endowment. Prof. EL Abbadi’s main research interests and accomplishments have been in understanding and developing basic mechanisms for supporting distributed information management systems, including databases, digital libraries, peer-to-peer systems, and spatial databases.
