Self-Tuning Database Systems: A Decade of Progress

In this paper we discuss advances in self-tuning database systems over the past decade, based on our experience in the AutoAdmin project at Microsoft Research. This paper primarily focuses on the problem of automated physical database design. We also highlight other areas where research on self-tuning database technology has made significant progress. We conclude with our thoughts on opportunities and open issues. 1. HISTORY OF AUTOADMIN PROJECT Our VLDB 1997 paper [26] reported our first technical results from the AutoAdmin project that was started in Microsoft Research in the summer of 1996. The SQL Server product group at that time had taken on the ambitious task of redesigning the SQL Server code for their next release (SQL Server 7.0). Ease of use and elimination of knobs was a driving force for their desig
