How can i get 3 table data in index in laravel?

I have 3 tables schools, school_Details,ratings

** Schools**

• id

• name

• phone

• school

• email

• status

School details:

-id

• school_id

• image

• status

ratings:

-id

• school_id
• rating_value
• status

both rating &school details have only one row for one school_id.

Now how can i get all details from all 3 tables in index from schoolController
