Redirection Logic: This is the backend logic that will take the quick URL and redirects the user for the corresponding prolonged URL. This logic is usually applied in the online server or an application layer.

Base62 Encoding: A single typical technique is to utilize Base62 encoding (which works by using 62 figures: 0-nine, A-Z, along with a-z) on an integer ID. The ID corresponds to the entry while in the database. This technique makes sure that the small URL is as shorter as you possibly can.
Random String Technology: A different tactic would be to crank out a random string of a set size (e.g., six figures) and Look at if it’s now in use in the databases. If not, it’s assigned for the lengthy URL.
four. Database Administration
