Database plug-in?

I’m building a site for a summer hockey tournament. I added the Contact Form 7 to Database Extension plugin to the site so when users fill out the registration form their data will be uploaded to the rosters page (not active yet)

I was wondering if there was a plugin that would allow me to create a database for the players and keep track of their stats during the tourney, (goals, assists, etc.) I saw a plug-in called custom tables that seemed like something I might be able to use and wanted to see if any of you have used it before, or have a better suggestion.

Databases are a huge weakness for me and I struggle trying to create them from scratch like you would on a regular html site.

Have you thought of trying on with this question.
