I’ve heard about this practice when you want to have more security or multi-platform soft, you need that something between client and server to handle request properly. For example no need to create database handlers on your mobile app and site, just send the same request to your something, what will deal with database and create JSON (whatever type you wanna get on your client) from SQL types.
