The Case for Determinism in Database Systems doc

... presents an intriguing future avenue of research. 3. THE CASE FOR NONDETERMINISM Before making the case for disallowing nondeterministic behavior in database systems, it is important to revisit the arguments ... transaction classes for which this may not be possible.
