What is the default table accessible upon login for Apps and Page

I assume that it is only the user profile table and that you need to have designed access around this table to get to the additional data that you will need in your application. This is how I have done it but was not sure if I am missing something fundamental.

I am week two into this adventure but have a working APP and PAGE. Need to refine row owner and user columns for multi-user experience and update the mediocre built-in data forms…Glide has been a great no-code solution.

BTW…Jack Vaughn, Robert Petitto and Darren Alderman plus Jesus Vargas and Dimitris Kamaritis have crafted great content. Glide documentation - NOT SO MUCH…

TIA … Matthew
