I need documentation . multi-store and multi-group development examples

[gusman126]

Hi, I have a client with Prestashop 1.6.1.x
It has multi-store enabled and also multiple store groups
Group 1 -> Store 1-1 -> Different design, products, customers, all different from other stores
Group 2 -> Store 1-1 -> Different design, products, customers, all different from other stores

I need to know how to perform the development to save the data only in
Group 2 - Store 1-1
I have not been able to find examples or documentation for these cases.
Much for multi-store, only 1 group, nothing multi-groups
