Base62 Encoding: A single widespread strategy is to employ Base62 encoding (which utilizes 62 figures: 0-9, A-Z, plus a-z) on an integer ID. The ID corresponds for the entry within the database. This method makes sure that the small URL is as small as feasible.
Random String Generation: An additional solution will be to crank out a random string of a set duration (e.g., 6 figures) and Check out if it’s now in use within the databases. If not, it’s assigned on the extended URL.
