Does my updated landing page tell you what I'm offerring?

SQL Schema Explorer - Get the best view of your database

I've rewritten pretty much my entire landing page. I'd love some feedback on whether you can tell what I'm trying to offer. I'd be particularly interested if you're left with any outstanding questions, and whether there's enough there to get you through to the sign-up form. If you wouldn't mind letting me know whether you know anything about databases yourself that would be helpful context.

Thank you all so much for all the feedback from last time, I still haven't finished working through it all, but hopefully you can see improvements from where I have managed to act on it. I know the design is still a bit amateur, that's quite high on my list to sort out.
