Hi,
If you would like your events manager to edit or update the rows/columns of data for your events database, you can create a form, add a text input, or create some kind of interaction that triggers a function that updates specific information about an event.
A form is one of the most common ways to add or update data in a database in my experience.
Take a look at the Corvid reference for the update() function here .
I was able to find a similar question here regarding the update() function.
If you would like to add a new event to the database, take a look at the insert() function here.
Take a look at the Corvid examples here to see some examples on how to add or update data within a database on your site.
Best regards,
