Base62 Encoding: A person common technique is to work with Base62 encoding (which works by using 62 figures: 0-9, A-Z, plus a-z) on an integer ID. The ID corresponds towards the entry inside the database. This method makes sure that the limited URL is as limited as you can.
Random String Technology: A further tactic is usually to crank out a random string of a fixed duration (e.g., 6 characters) and Look at if it’s presently in use during the database. If not, it’s assigned into the extended URL.
