Can you give an example of a situation where a database is used to store information?

A database is used to store information when you need to save data between application launches and provide quick access to it. For example, in an iOS note-taking app, a database (such as Core Data or SQLite) can be used to save note text, creation date, and other metadata. This allows users to create, edit, and delete notes, with data stored locally and accessible upon the next app launch.
