Base62 Encoding: Just one common method is to implement Base62 encoding (which makes use of 62 people: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds to the entry inside the databases. This method ensures that the limited URL is as quick as is possible.
Random String Technology: An additional technique should be to crank out a random string of a set size (e.g., 6 figures) and Check out if it’s presently in use in the databases. Otherwise, it’s assigned on the prolonged URL.
