Question: 1. Consider the ER schema of relation F=(A,B,C,{D},E,F). Knowing that there are the following (functional) dependencies: fd1: {A}{C,E}, fd2: {A}{D},fd3:{A,B}{F}. - Is F in 1NF?

1. Consider the ER schema of relation F=(A,B,C,{D},E,F). Knowing that there are the following (functional) dependencies: fd1: {A}{C,E}, fd2: {A}{D},fd3:{A,B}{F}. - Is F in 1NF? If "yes" why? If not modify F so as to put it in 1NF. Let us call F1 the result of this step - Is F1 in 2NF? If "yes" why? If not modify F1 so as to put it in 2NF. Let us call F2 the result of this step - Is F2 in 3NF? If "yes" why? If not modify F3 so as to put it in 3NF
