Working with Database when in Basic version!

I would like to know if I can work with Databases if in a basic version? I see a few database extensions in the pro version hence wondering if the basic version would limit db connectivity in any way? Note that I used to work in DW in 2005 and off late have started web development once again but in Joomla. Wappler Seema like a tool that I have been looking for and not being an expert coder or at least not my favorite thing to do, I see wappler nailing it down for me.
