First and Second NF

Hello

i got a table with a single column primary key. It is in the first nf. Afaik is the condition for the second nf that all values that are not key-values have to depend on the _entire_ primary key. Because in the table pk is only on column this table is automaticlly in the second nf.

Comments are welcome.
