Base62 Encoding: One prevalent technique is to employ Base62 encoding (which employs sixty two people: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds to the entry within the databases. This technique ensures that the shorter URL is as small as you can.
Random String Generation: An additional technique is always to create a random string of a hard and fast duration (e.g., six figures) and check if it’s by now in use inside the databases. If not, it’s assigned to the long URL.
4. Databases Administration

ID: A singular identifier for every URL entry.
Prolonged URL: The first URL that needs to be shortened.
Brief URL/Slug: The small version on the URL, normally stored as a singular string.
