Paper Review: Generalized Isolation Level Definitions | Kevin Sookocheff

| | Title and Author of Paper Generalized Isolation Level Definitions, Adya et al. Summary The ANSI SQL standard defines isolation levels allowing database users to trade off between performance and consistency when running transactions. Unfortunately, the wording in the SQL standard is geared towards locking as the sole supported concurrency method. This paper presents alternative definitions to the isolation levels specified in the ANSI SQL standard that are general enough to allow for any concurrency method (multi-version, optimistic, etc.) to be used.
