Mastering the Basics of SQL Server Query Optimization

Student Warning: Even though this is a beginners class it’s fast paced and will require some outside study on your part.
I’ve included 4 different preview lessons so you could better gauge the speed of the course. Please take a moment to preview all of them. If those lessons are too fast then please take this course after you’ve taken my entry level courses. Thanks…. Mike

In this course we are going to delve into the Query Optimizer, easily one of the most complicated pieces of software ever written.
The Query Optimizer is the SQL Server component that tries to give you an optimal execution plan for your queries. The Query Optimizer tries to find that execution plan as quickly as possible. Not the perfect plan but a good one.
The SQL Server Query Optimizer is a cost-based optimizer. It analyzes a number of execution plans for a given query, estimates the cost of each of these plans, and chooses the plan with the lowest cost.
The optimizer seeks to find balance between the optimization time and the quality of the selected plan.
The course will be a balance of hands on query performance tuning and understanding the basics of the optimizer’s architecture.
We are going to learn about the execution engine, statistics and cost estimation, index selection and the optimization process.
At the core of the SQL Server Database Engine are two major components: the storage engine and the query processor also called the relational engine.
In this course our sole focus will be on the query processor. This part of the engine accepts all queries submitted to SQL Server and creates a plan for optimal execution.
See you in the course!!!
