Microsoft SQL is Microsoft's database server. This video will run you through the installation process of Microsoft SQL Server. I am using SQL Express but the installation process is the same for installing the paid version of SQL as well as the express version.
As an IT Administrator you will most likely need to install SQL at some point because a lot of software products in businesses us SQL as their backend database.
This video is designed for a person who is new to IT and needs to install SQL server.
