Delve inside the core SQL Server engine - and put that knowledge to work - with guidance from a team of well-known internals experts. Whether database developer, architect, or administrator, you´ll gain the deep knowledge you need to exploit key architectural changes- and capture the product´s full potential.

Discover how SQL Server works behind the scenes, including:

• What happens internally when SQL Server builds, expands, shrinks, and moves databases
• How to use event tracking - from triggers to the Extended Events Engine
• Why the right indexes can drastically reduce your query execution time
• How to transcend normal row-size limits with new storage capabilities
• How the Query Optimizer operates
• Multiple techniques for troubleshooting problematic query plans
• When to force SQL Server to reuse a cached query plan - or create a new one
