I am wondering two things, actually a lot more but let’s start here.
First is there any similar data table layout documentation for version 5.3.3? I found this one (https://help.x-cart.com/index.php?title=X-Cartatabase_layout
The second question: We are much better mySQL/Nodejs programmers than PHP programmers. What are the implications of just doing direct data inserts and updates into the data tables for adding/updating products, categories, and orders?
