The last several versions of Microsoft’s SQL server have seen the introduction of a number of new features. However, not all users will find these necessary, and many may wish to turn to the more lightweight SQL Server Express instead.
In this tutorial we offer a step-by-step guide to installing, testing, upgrading, and uninstalling SQL Server Express 2019.
