The 5 day class offers a comprehensive coverage of SQL Server architecture, indexing and statistics strategies, optimize transaction log operations, tempdb and data file configuration, transactions and isolation levels, and locking and blocking. The course also teaches how to create baselines and benchmark SQL Server performance, how to analyze workload and figure out where performance problems are, and how to fix them. The course has a special focus on SQL Server I/O, CPU usage, memory usage, query plans, statement execution, parameter sniffing and procedural code, deadlocking, plan cache, wait and latch statistics, Extended Events, DMVs and PerfMon. Audience Profile The primary audience for this course is individuals who administer and maintain SQL Server databases and are responsible for optimal performance of SQL Server Instances that they manage. These individuals also write queries against data and need to ensure optimal execution performance of the workloads. The secondary audiences for this course are individuals who develop applications that deliver content from SQL Server databases.
