David J. DeWitt is the John P. Morgridge Professor (Emeritus) of Computer Sciences at the University of Wisconsin–Madison. Professor DeWitt received a B.A. degree from Colgate University in 1970, and a Ph.D. from the University of Michigan in 1976. He then joined the University of Wisconsin-Madison and started the Wisconsin Database Group, which he led for more than 30 years.
Professor DeWitt is known for his pioneering research in the areas of parallel databases, benchmarking, object-oriented databases, and XML databases. He is an elected member of the National Academy of Engineering (1998),[1] and a Fellow of the Association for Computing Machinery.
He received the ACM SIGMOD Innovations Award (now renamed SIGMOD Edgar F. Codd Innovations Award) in 1995 for his contributions to the database systems field. In 2009, ACM recognized the seminal contributions of his Gamma parallel database system project with the ACM Software System Award. Also in 2009, he received the IEEE Emanuel R. Piore Award for his contributions to the database systems field.[2]
Currently, he is a technical fellow at Microsoft, leading the Microsoft Jim Gray Systems Lab at Madison, Wisconsin.
The "DeWitt Clause"
Several commercial database vendor's end-user license agreement includes a provision, known as the DeWitt Clause that prohibts researchers and scientists from explictly using their systems' names in academic papers. [3][4] In essence, DeWitt Clauses forbid the publication of database benchmarks that the database vendor has not sanctioned. The original DeWitt clause was established by Oracle at the behest of Larry Ellison. Ellison was displeased with a benchmark study done by David DeWitt in 1982, then just an assistant professor, using his new Wisconsin Benchmark that showed that Oracle's system had poor performance.[5] Ellison called Wisconsin's department chair and demanded by that DeWitt be fired. After the department refused, Ellison personally banned Oracle from hiring any students from the University of Wisconsin and changed their license to prevent anyone else from mentioning Oracle by name in a benchmark study.[6]
