We have a database with the following attributes and tuples: CustomerId$(182,201,153),$ CustomerName$($PETROV$,$ IVANOV, GEORGIEV$),$ CarId$($CH$1236,$ CB$8095,$ A$4256),$ MANUFACTURER$($MERCEDES$,$ FORD, VOLVO$),$ DATE$(12-04-18,27-05-2018,21-12-2017).$ What is the key? Explain why based on the relational model. In the same table, identify the non$-$trivial functional dependencies significant for normalization. In which normal form is the table? Explain why based on the relational model. If necessary, normalize to $3$NF$,$ explaining each normalization step. Indicate the relational schemas in the normalized version, and write the SQL code for creating the relations and constraints. I want detailed anwer and every table shown
