Nice work! You’ve not only connected your web app to an external database, you’ve also given the UI functionality to add, edit and delete items in that database.

Using an Uplink script to connect to systems outside of Anvil is very powerful. You can generalise this approach to solve a whole host of problems.

For example, you could use the Uplink to run machine learning models on your own cluster and return the results to Anvil (and use a Background Task to do this asynchronously). Or you could use an Uplink script as a gateway to communicate with IoT devices inside your network.

Anything you can do with Python, you can control with an Anvil app via the Uplink.

For a comprehensive view of what the Uplink can do, check out the Uplink section of the reference docs:
