Understanding and using indexes on SQL Server

About

My videos are mostly about software development since that's my job! I develop web applications for a living so I have experience across a variety of languages and technology including some hardware knowledge picked up along the way. I am the founder of https://www.cotswolditconsulting.co.uk so it is good exercise for me to make videos! I hope you find the videos useful, just hit "like" or comment. I also take requests!
