Base62 Encoding: A single popular method is to employ Base62 encoding (which employs sixty two people: 0-nine, A-Z, along with a-z) on an integer ID. The ID corresponds to the entry from the database. This process ensures that the short URL is as small as possible.
Random String Era: Another technique is to make a random string of a fixed duration (e.g., 6 people) and Verify if it’s presently in use during the database. Otherwise, it’s assigned to the extensive URL.

باركود وجبة فالكون كودو
ID: A unique identifier for every URL entry.
Long URL: The initial URL that should be shortened.
Brief URL/Slug: The limited Variation in the URL, normally stored as a singular string.
