The objective of this course is to provide senior database analysts and developers with a good understanding of SQL Server Architecture and Query Performance so that applications and their underlying queries, indexing and locking strategies can be tuned for optimal performance. The course will provide delegates with the knowledge required to tune and troubleshoot a SQL Server application for either a OLTP live environment or a OLAP data warehousing environment. Everything from Operating System & SQL Server architecture through to query and index monitoring & tuning will be covered. It is a hands on course with performance and analysis tools being put to use throughout. Delegates will learn how to capture and analyse performance data to enable troubleshooting of performance problems using tools such as SQL Profiler, Extended Events, Execution Plans and Dynamic Management Views. They will learn how to interpret query execution plans to determine where the cause of bottlenecks lies and how to tune the queries for best performance. Covers all versions from SQL Server 2008 through to SQL Server 2017.
