(Currently considering evaluating the product for purchase.  Haven't installed it yet.)

I don't see SQL or MySQL mentioned in some of the downloadable documentation, but I see references to it on the above link.

 

I'm confused...  Does the product come with a "built-in database", but perhaps SQL or MySQL should be considered for larger installations?
