So, to clarify, it looks like you are already using Google Sheets, which is great.

But the spreadsheet you link to is designed more “visually” and not like a real database. You also don’t seem to be accounting for 1-to-Many and Many-to-Many relationships in the data.

Also, from the way you phrase your question, it sounds like you say “a database” but mean “a database and an app to manage it.”

Am I close?

If that’s the case, I’d suggest to begin with watching a few YouTube videos on “database design” to understand things like “primary keys” and 1-to-Many and Many-to-Many relationships. And then focus on designing just the tables of your database. Possibly, just using Google Sheets and with a little help from an experienced freelance developer.

Once you get the tables right, you can think about the app. A few options there would be Google Sheets, Airtables, Bubble.is, or even using something like MySQL and a custom-built app.
