Abstract
We present a retrospective on key contributions of the Clio project, a joint project between the IBM Almaden Research Center and the University of Toronto begun in 1999. Clio’s goal is to radically simplify information integration, by providing tools that help in automating and managing one challenging piece of that problem: the conversion of data between representations.
Clio pioneered the use of schema mappings, specifications that describe the relationship between data in two heterogeneous schemas. From this high-level, non-procedural representation, it can automatically generate either a view, to reformulate queries against one schema into queries on another for data integration, or code, to transform data from one representation to the other for data exchange. In this talk, we focus on two key components of Clio: the creation of mappings between heterogeneous schemas, and their use for the implementation of data exchange.
Speaker's bio
Renee J. Miller is a professor of computer science and the Bell Canada Chair of Information Systems at the University of Toronto. She received the US 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 received an NSF CAREER Award, the Premier's Research Excellence Award, and an IBM Faculty Award. Her research interests are in the efficient, effective use of large volumes of complex, heterogeneous data. This interest spans data integration and exchange, inconsistent and uncertain data management, and data curation and cleaning. She serves on the Board of Trustees of the VLDB Endowment and served as PC co-chair of VLDB in 2004. She received her PhD in Computer Science from the University of Wisconsin, Madison and bachelor's degrees in Mathematics and Cognitive Science from MIT.
