Base62 Encoding: One particular prevalent strategy is to use Base62 encoding (which makes use of 62 figures: 0-9, A-Z, as well as a-z) on an integer ID. The ID corresponds to the entry inside the databases. This method ensures that the shorter URL is as shorter as you possibly can.
Random String Technology: Another strategy would be to generate a random string of a hard and fast length (e.g., six characters) and Look at if it’s now in use while in the databases. If not, it’s assigned to your lengthy URL.
