How I GET the data from JSON structure?

cishpix

Hi all,
I want GET data from other application by API (see the below for the JSON structure)

I have 4 BO and every BO have an attribute that I set peer relation with other BO.
Currently, I already can get the data for item_details BO but I'm stuck when want catch the data for category_detail BO. If I check the table of category BO in my database, the count of records already same with count of records in item_details BO.
So, my question is how can I get the data for category_detail?

FYI, I have try set the peer relation that support multiple but still no luck

You should have:
1) CategoryDetail BO with attributes:
a) id
b) name
c) type
2) Category BO with attributes:
a) data (of type CategoryDetail single)
3) ItemDetails BO with attributes:
a) id
b) name
c) description
d) category (of type Category single)
4) Response BO with attributes:
a) data of type ItemDetails multiple

Interesting how Vlad's brain processes this in reverse order of how I would imagine it.

Thank you Support, I was already designed like your comment but no luck so that's why I open this thread with my design as attachment.
After I worst a day, I found the answer now. Maybe every API can different, so I solve it with merge all attributes from category_detail BO into category BO
