The index on Customers(Email) is appropriate and correctly named, but the requirements imply you should also consider other frequently-used or join columns (e.g., CustomerID in Orders, OrderID and ProductID in OrderItems).

CREATE INDEX Name ON Products(Name);

Similarly, the index on Products(Name) is valid, but the task expects a broader analysis of the schema; consider adding indexes for relationship/lookup columns in Orders and OrderItems as well.

CREATE INDEX CustomerID ON Orders(CustomerID);
CREATE INDEX OrderID ON OrderItems(OrderID);
CREATE INDEX ProductID ON OrderItems(ProductID);
