Base62 Encoding: One prevalent strategy is to implement Base62 encoding (which uses 62 people: 0-9, A-Z, along with a-z) on an integer ID. The ID corresponds into the entry while in the databases. This method makes certain that the small URL is as brief as is possible.
Random String Technology: An additional strategy is usually to make a random string of a fixed size (e.g., 6 characters) and check if it’s now in use from the databases. If not, it’s assigned towards the extended URL.
