The difference is that while standard aggregate functions will return computation results. For more complex properties (object, array, or other complex types), an "Edit" button in the cell creates a nested Editor (type chosen automatically) for editing the nested object. In the previous section we assumed the models are already there and we just want to create a matching JSON. Each entry (key/value pair) is separated by comma. The home of JSON Schema. Plus, it sheds more light on how it works alongside to_json() and from_json() functions when extracting attributes and values from complex JSON structures.
