Base62 Encoding: One particular prevalent solution is to implement Base62 encoding (which employs sixty two people: 0-9, A-Z, plus a-z) on an integer ID. The ID corresponds to your entry inside the databases. This technique makes sure that the limited URL is as small as possible.
Random String Era: One more technique is usually to crank out a random string of a fixed size (e.g., 6 figures) and Look at if it’s previously in use inside the database. If not, it’s assigned on the prolonged URL.
