Abstract:

Data integration is the problem of providing an integrated, virtual view of a set of heterogeneous sources that can be used for query answering. Data exchange is the problem of taking data structured under a source schema and creating a (materialized) instance of an independent target schema that reflects the source data as accurately as possible. Data exchange is important in many networked applications involving the translation or migration of data between database systems, applications, or enterprises. In this talk, we present an overview of work on data integration. We then present some new results on data exchange that are providing the groundwork for understanding how data can be shared between autonomous (independently developed and managed) data sources. We will illustrate how the management of incompleteness and inconsistency are central to query answering in data sharing environments. (Joint work with Ron Fagin, Phokion Kolaitis, Lucian Popa, and Yannis Velegrakis.)

Speaker Bio:

Renee J. Miller is an associate professor of computer science at the University of Toronto. She received the 1997 Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the United States government on outstanding scientists and engineers beginning their careers. She is a recipient of the NSF CAREER Award, the Premier's Research Excellence Award, and an IBM Faculty Award. She is currently serving as PC co-Chair for VLDB 2004. Her research interests are in the efficient, effective use of large volumes of complex, heterogeneous data. This interest spans heterogeneous databases, peer-to-peer data management, and data mining.
