Base62 Encoding: A person common approach is to make use of Base62 encoding (which takes advantage of 62 figures: 0-nine, A-Z, as well as a-z) on an integer ID. The ID corresponds to your entry from the databases. This method ensures that the quick URL is as quick as you possibly can.
Random String Technology: Another approach is always to make a random string of a set length (e.g., six characters) and Verify if it’s previously in use inside the database. Otherwise, it’s assigned into the long URL.
