We need to define some functionalities which we will need, and some of the general requirements are the following:

• Redirection: This functionality should redirect the short URL to the actual URL so the request can be successfully entertained.
• Customized short URL: This functionality should allow the user to generate unique and customized short URL alias of the original URL.
• Deletion: This functionality should allow users to delete the generated short URL.
• Updation: This functionality should allow the user to update the original URL associated with it.
• Expiry time: This functionality should allow users to set the expiry time of the generated short URL.

Non-functional requirements

We have decided that our system should have the following behavior, which is not functional:

• Availablity: We want our system to be available at all times at any cost because we want our users to access any URL anytime.
• Scalability: We want our system to be capable enough to handle an increasing number of URLs.
