Base62 Encoding: One particular common strategy is to employ Base62 encoding (which uses 62 characters: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds for the entry within the database. This process makes certain that the brief URL is as limited as is possible.
Random String Technology: One more approach would be to create a random string of a fixed size (e.g., 6 characters) and Examine if it’s by now in use in the databases. Otherwise, it’s assigned into the long URL.
4. Database Management
The database schema for the URL shortener is frequently clear-cut, with two primary fields:

ID: A novel identifier for each URL entry.
Extensive URL: The original URL that needs to be shortened.
Small URL/Slug: The limited Variation in the URL, generally saved as a unique string.
