Information Technology - Database Language SQL

Draft of the ANSI SQL 92 specification (final specification only available for purchase, see http://ansi.org/).

"A Critique of ANSI SQL Isolation Levels"

H. Berenson, P. Bernstein, J. Gray, J. Melton, E. O'Neil, and P. O'Neil. A critique of ANSI SQL isolation levels. In Proceedings of the ACM SIGMOD International Conference on Management of Data, pages 1-10, June 1995.



"(Abstract) ANSI SQL-92 defines Isolation Levels in terms of phenomena: Dirty Reads, Non-Repeatable Reads, and Phantoms. This paper shows that these phenomena and the ANSI SQL definitions fail to properly characterize several popular isolation levels, including the standard locking implementations of the levels covered. Ambiguity in the statement of the phenomena is investigated and a more formal statement is arrived at; in addition new phenomena that better characterize isolation types are introduced. Finally, an important multiversion isolation type, called Snapshot Isolation, is defined."

This document provides a nice survey of transaction isolation levels in general, and some detail on "snapshot" isolation, which is the transaction isolation level currently supported by Axion.
