Costs of Concurrency (Kalen Delaney)
Author: Greg Linwood Date Posted: 9/08/2007 4:51:36 PM
SQL Server 2005 offers two models for an application to provide data consistency: Pessimistic and Optimistic Concurrency Control. In this session we’ll discuss what consistency might mean to your applications, and describe the costs and tradeoffs between the two Concurrency Models that SQL Server 2005 supports through different transaction isolation levels. We’ll also look at the internal differences between the isolation levels.
