Best Practices to store user owned items

Hello @Antviss

I think this thread provides enough information on how to approach your objective (link). In case you opt for a more fine-grain control over read and/or writes using custom SQL with json specific functions, I would recommend that you change the items from a list to an object (alternative 2). That way you can add and remove elements easily O(1) from the data structure without iterating over the elements to find them O(n).
