To ensure that queries run as efficiently as possible, the database administrator needs to monitor performance to find inefficient queries. This article focuses on exploring how a DBA can monitor the I/Os against an instance of SQL Server, using Dynamic Management Objects, or more commonly know as Dynamic Management Views (DMVs) and Functions (DMFs).
Today Steve Jones looks at the new release of restore technology from Red Gate software that allows you to "fool" SQL Server.
