Approximate (uncertain, probabilistic, incomplete, fuzzy, imprecise!) databases have been proposed in past, problem has studied. The goals project are to distill previous work into simple usable model, design query language as an understandable extension SQL, most importantly build working system---a augments conventional data management with both integral part This paper provides numerous motivating applications for lays out preliminary plans language, prototype system.
