Database
A database is where an app stores its information so it is saved, organized, and findable later.
Think of it like
A giant, super-fast filing cabinet that an app reads from and writes to thousands of times a second.
Example
Your username, posts, and settings all live in a database, so they are still there when you log back in.
Why it matters
Almost every real app has one. “The data is in the database” is a sentence you will hear constantly.
