Jennifer Widom introduced the fundamental concepts and architectures of active database systems, a major area of research in the database field today. Active database systems allow application developers to embed logic into the database that allow actions to be executed when certain conditions are met. Active database systems have had a major impact on commercial database management systems, and most modern relational databases include active database features.
Widom made fundamental contributions to the study of semi-structured data management. Semi-structured data management systems are a key technology to support many advanced applications today, such as genomic databases, multimedia applications and digital libraries. Widom led the Lore project, which made important contributions on how to share, index and query semi-structured data sets, and developed the Lorel query language. Lorel has had a major impact on the research community, and many of its concepts have been applied to the design of query languages for XML data.
The Athena Lecturer is invited to present a lecture at an ACM event. Widom’s lecture will be delivered on June 2, 2015 at the 2015 ACM SIGMOD Conference in Melbourne, Australia.
