Base62 Encoding: One particular popular method is to use Base62 encoding (which employs 62 characters: 0-9, A-Z, along with a-z) on an integer ID. The ID corresponds on the entry during the database. This method makes sure that the brief URL is as quick as feasible.
Random String Technology: A further strategy will be to generate a random string of a fixed length (e.g., six figures) and Check out if it’s already in use in the database. If not, it’s assigned on the very long URL.
