SQL Server Performance Tuning Training (Online)

By Neeraj, Microsoft Certified DBA!!! (*****)

Course Description

Our SQL Server Performance Tuning and Optimization course will give you a practical optimization technique to put into production. We ensure you understand WHY and HOW a technique works rather than just what the technique is all about.

As well as optimization techniques, this course will also help with design and architecture so you can prevent performance and scalability problems from happening. All the modules will be addressed on multiple fronts: how SQL Server works, implementation considerations and techniques, common problems, troubleshooting, and resolutions.

This course is essential for all SQL Server Developers, DBAs, Data Engineers, and Architects.
