Issue with tree structure

Hi Experts,

I have created a SAPUI5 application which mock json data, the master page is in tree structure as shown in image, image1 which is working fine.

The excel sheet snapshot is my mock json representation, using this data only i am creating my mock json.

Now the same application has to be build using odata service as backend(without using mock json data). How could i able to give my master page view as a tree structure in a odata service. Please guide me and help me.
