Base62 Encoding: 1 prevalent tactic is to work with Base62 encoding (which uses 62 people: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds to your entry in the databases. This method ensures that the brief URL is as shorter as is possible.
Random String Technology: Another strategy should be to create a random string of a set size (e.g., 6 people) and check if it’s currently in use within the database. Otherwise, it’s assigned to your long URL.

ID: A unique identifier for every URL entry.
Long URL: The initial URL that should be shortened.
Brief URL/Slug: The limited Variation from the URL, often stored as a singular string.
