Database
(DB)
An organised collection of data that can be stored, searched and updated reliably
What's it for?
Stores organised information so software and people can find, change and use it reliably.
For example…
Sales, support and billing read customer details from the same database
An online shop stores customers, products and orders in a database so thousands of users can read and update records safely at the same time
Think of it like…
A database is like a filing cabinet with labelled drawers and rules about what belongs where—not a single giant desk pile
