Back-End koosneb serverist, rakendusest ja andmebaasist. Back-End arendaja loob ja hooldab tehnoloogiat, keskendudes nendele komponentidele, mis tagavad selle, et veebisaidi kasutajapoolne vaade saaks üldse eksisteerida.

The Back-End of a website consists of a server, an application, and a database. A back-end developer builds and maintains the technology that powers those components which, together, enable the user-facing side of the website to even exist in the first place.
