Base62 Encoding: Just one typical solution is to make use of Base62 encoding (which works by using 62 figures: 0-9, A-Z, and also a-z) on an integer ID. The ID corresponds on the entry from the databases. This process makes certain that the short URL is as shorter as is possible.
Random String Generation: Yet another technique is always to produce a random string of a fixed size (e.g., six people) and Examine if it’s presently in use inside the databases. If not, it’s assigned for the extensive URL.
