Since their invention in the early 70s, relational databases have been deterministic. They were designed to support applications s.a. accounting, inventory, customer care, and manufacturing, and these applications require a precise semantics. Thus, database systems are deterministic. A row is either in the database or is not; a tuple is either in the query answer or is not. The foundations of query processing and the tools that exists today for managing data rely fundamentally on the assumption
