Thank your for your reply. Actually I created another model that aggregates all the values from each group table. but after analyzing I feel its a worst method and performance is also very low.So model re-design is the only way to sort out this issue and need help for redesigning the models. Because I want to add users and map these users to group details from the admin page. I am very confused state and I don't know how to re-design and optimize the queries.
