09:2609:26, 9 June 2021 diff hist +102‎ Unnormalized form ‎ Rewrote introduction to clarify and to mention related concepts of NoSql and denormalization

20:0120:01, 8 June 2021 diff hist −423‎ Unnormalized form ‎ Removed misleading example
17:1717:17, 8 June 2021 diff hist −1‎ Talk:Database normalization ‎ →Non-repeating groups
17:1517:15, 8 June 2021 diff hist +750‎ Talk:Database normalization ‎ →Non-repeating groups
17:0817:08, 8 June 2021 diff hist +396‎ Talk:Database normalization ‎ →Non-repeating groups
16:1116:11, 8 June 2021 diff hist −916‎ Unnormalized form ‎ Deleted the overview section since the text seem to be nonsense. Tag: section blanking
16:0616:06, 8 June 2021 diff hist +111‎ Database normalization ‎ Remove misleading use of the term "repeating group" and clarified language
15:2615:26, 8 June 2021 diff hist −170‎ Database normalization ‎ Removed incorrect reference to "repeating groups". Repeating groups is a confusing term, but the way Codd uses it, it refers to nested records, which is what 1NF eliminates.
15:1215:12, 8 June 2021 diff hist −831‎ Database normalization ‎ Corrected explanation of first normal form. Previous text conflated different normalization levels and issues unrelated to normalization.
14:5714:57, 8 June 2021 diff hist +38‎ Database normalization ‎ Adding primary key to examples
14:5514:55, 8 June 2021 diff hist +630‎ Database normalization ‎ Added primary key to example - otherwise table is not relational and normalization does not apply
14:2814:28, 8 June 2021 diff hist +32‎ Database normalization ‎ More consistent visualization of non-simple domain
09:4509:45, 8 June 2021 diff hist −142‎ First normal form ‎ Explain normalization process, with reference to Codd
08:1208:12, 8 June 2021 diff hist +920‎ First normal form ‎ Added an overview section and updated text around it

18:3818:38, 7 June 2021 diff hist +143‎ First normal form ‎ Add reference
18:2818:28, 7 June 2021 diff hist −1,221‎ First normal form ‎ Remove misleading example. Multiple columns with same domain is explicitly allowed in 1NF, as long as they have distinct names.
17:5317:53, 7 June 2021 diff hist +44‎ First normal form ‎ Change misleading example. A comma separated string is not a violation of 1NF. First Normal form is about disallowing the nested structures known from hierarchical databases.
