These are basic examples of Shiny apps performing CRUD (Create, Read, Update, Delete) database operations. In this case I used a Posgresql db on a Heroku instance to store and retrieve data which are then loaded into the shiny app dockerized and hosted into GCP.
I added CRUD functionalities to a dataset containing some interesting facts happened in the past that can be potentially relevant!
I am always looking to improve myself, feel free to suggest!
