Line 514: This section seem to contain the definition of "relation" rather than the definition of 1NF. Data being in relational form is a prerequisite for 1NF, but it is not the ''definition ''of 1NF since we can have relations which are ''not ''in 1NF - after all, normalization is defined as bringing non-1NF relations into 1NF. So I suggest either removing this section altogether or moving it to another article, perhaps [[Relation (database)]].
