Actually this is not true. My browser does not connect to medium database. What happens here (if we exclude DNS stuff), is that client, calls medium server to get data. Medium server connects to database, and fetches relevant data. This data is the incorporated with the UI. This UI is then „sent“ to client browser and client browser turns that HTML into something that user can see. This is roughly what happens. And no, you cannot say that browser connects to database. That would be serious se urity concern
