1. What Is SQL and Why Analysts Need It
1.4 What Is a Database File (SQLite) vs a Database Server
Why. Beginners fear installing a server. SQLite removes that fear.
What. SQLite stores a whole database in one file (.db). A database server (PostgreSQL, MySQL, SQL Server) runs as a service and many apps connect to it.
How. This course starts with a .db file you open in DB Browser. Same SQL ideas transfer to servers later.
Steps

- Open it in DB Browser for SQLite.
- You are connected — no password, no port.
