Base62 Encoding: One particular typical approach is to implement Base62 encoding (which utilizes sixty two people: 0-nine, A-Z, along with a-z) on an integer ID. The ID corresponds to the entry during the database. This technique makes certain that the shorter URL is as small as is possible.
Random String Technology: A further tactic is usually to make a random string of a set size (e.g., six figures) and Test if it’s already in use within the databases. If not, it’s assigned for the extended URL.

ID: A unique identifier for each URL entry.
Long URL: The initial URL that should be shortened.
