New Isolation Levels Available in SQL Server 2005

http://www.sql-server-performance.com/articles/per/new_isolation_levels_p1.aspx



In SQL Server 2005, two new isolation levels are introduced, both of which use row versioning. They include:

READ_COMMITTED_SNAPSHOT (statement level)
ALLOW_SNAPSHOT_ISOLATION (transaction level)

'READ_COMMITTED_SNAPSHOT' isolation level is especially useful for applications that you migrate from platforms that support obtaining
earlier consistent versions of data, such as when an application migrates from Oracle to SQL Server.
