What does an SQL Server actually do?

If you have heard people talk about SQL, SQL Server, databases, local databases, SQLite, PostgreSQL, MySQL, or Microsoft SQL Server and wondered how all of those pieces fit together, this video is for you.

In plain English, Dean explains:

- what SQL is
- what Microsoft SQL Server is
- what a database server does
- how a local database is different
- why transactions and permissions matter
- when a SQL/database server makes sense
- when a spreadsheet or local database is enough

This is not a full SQL tutorial. It is the mental model that makes the rest of the database world easier to understand.
