DML operations in detail

DML is used in most cases without thinking about the multiple operations for the db engine. This session will do a deep dive into the internal storage engine down to record level.

After finishing the theory (and inside the theory) the differen DML commands and their tremendous operational tasks for the db engine will be investigated.
SEE, what a workload will be caused by a "forwarded record". What tremendous workload will occur in a page split. What happens if an existing record will be updated in fixed length attributes

Get aware of the huge amount of transaction log may be generated when a simple page split occurs.
Learn techniques to avoid cost expensive operations

Uwe Ricken was the first MCM + MVP in Germany! To provide his deep knowledge about Microsoft SQL Server to the interested community Uwe is blogging since 2010 at http://db-berater.blogspot.de about his daily experiences with Microsoft SQL Server. His blog posts are in German language only to provide the German speaking SQL community a deeper inside view into the technology of Microsoft SQL Server.
