Must know software terms | Noun
the software equivalent of the Wizard of Oz. Sits behind a curtain, people come to him with stupid requests. The backend designates the data access layer, as opposed to the frontend which is the presentation layer. Backend can refer both to the code which handles data storage and requests and the physical infrastructure which makes this possible (e.g. in a server-client model, the client is the frontend and the server is the backend). In short, everything that happens before the page is displayed in a browser is part of the backend, from processing an incoming request to running a script to generate HTML or encrypting and decrypting data.
“What's the best and worst part of being a backend developer?” “Users can't see my work.”
