Frequently asked questions

What is the difference between the back end and a database?

A database stores the data. The back end is the code that decides what may be read or written, checks permissions, applies the rules and returns results. A back end almost always talks to one or more databases, but the two are separate parts.

Does every website have a back end?

No. A purely static site — files served exactly as they were written — has no back-end application at all. Anything with logins, saved data, payments or personalised content does.

Why can't the back end run in the browser?

Anything sent to the browser can be read and altered by the person using it, so secrets such as passwords, keys and pricing rules are kept on the server where the user cannot reach them.
