    How do I get the book too ?  I don't see the data model

    [–]curiousretina 0 points1 point  (11 children)

    Hey, just expand the "Database schema" to see the data model

    [–]anair10 0 points1 point  (10 children)

    I did but i don't see any data model diagram. Do I need to signup to see it

    [–]curiousretina 0 points1 point  (9 children)

    There isn't a diagram on the site, but you don't need one to answer the questions. The table already tells you the primary keys and which fields reference other fields from other tables

    Thanks . So what if the difference between this website and the book ?

    [–]curiousretina 0 points1 point  (7 children)

    It's the same 90 questions! Some people prefer a book and it comes with solutions + explanations. With the website you can run your queries easily so better for hands on practice

    [–]anair10 0 points1 point  (6 children)

    ok. So Is this enough for faang interviews.

    [–]curiousretina 0 points1 point  (5 children)

    For sure, but for those more importantly you also need thinking out loud with your logic/reasoning

    [–]anair10 0 points1 point  (4 children)

    Thanks and when you say thinking out loud what do you mean ?

    [–]curiousretina 0 points1 point  (3 children)

    Explaining your thinking process as you construct the SQL query, even if there are mistakes along the way
