Base62 Encoding: One particular frequent method is to employ Base62 encoding (which works by using 62 figures: 0-nine, A-Z, and also a-z) on an integer ID. The ID corresponds for the entry during the database. This technique ensures that the limited URL is as short as you can.
Random String Technology: Another approach will be to crank out a random string of a hard and fast duration (e.g., six characters) and Test if it’s now in use in the databases. Otherwise, it’s assigned on the extended URL.
