Base62 Encoding: One particular prevalent solution is to use Base62 encoding (which utilizes sixty two people: 0-nine, A-Z, in addition to a-z) on an integer ID. The ID corresponds to the entry within the databases. This technique makes certain that the shorter URL is as small as you can.
Random String Generation: An additional method is always to produce a random string of a fixed duration (e.g., 6 characters) and Verify if it’s currently in use within the database. Otherwise, it’s assigned on the prolonged URL.
