Suggestions for type of directory/database set-up

Hello,
I’m starting up a WooCommerce store for affiliate cosmetics products. I was thinking of setting up a separate database that is password only for employees to post product research - products that they find with ingredients information, post their own comments, photos, and a rating of whether the product is approved by me, or declined. The reason why I wanted it to stay separate from the WooCommerce store is so employees don’t have access to wordpress, so that products in wordpress don’t get accidentally deleted/or posted under woocommerce to sell, and I can use this as a separate resource for internal product research.

Is there anything out there that I can use online to create my own database (I’m not a programmer) that is very simple to set up, password protected and does all the things I mentioned above?

Thanks
