Base62 Encoding: One particular frequent tactic is to work with Base62 encoding (which employs 62 characters: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds into the entry within the database. This process ensures that the small URL is as limited as is possible.
Random String Generation: A further approach is to crank out a random string of a fixed length (e.g., 6 people) and Verify if it’s currently in use during the database. If not, it’s assigned towards the long URL.
