Yes I found the Wiki, and other articles, but the whole topic of normalisation seems couched in academic terms.
I was trying to google for simple definitions of things like elemetary attribute key or prime attribute key - definitions that don't refer to other similar terms, sending my round in circles of cyclic definitions. I've since read your 3 normalisation articles, and heard mention that you may be planning a 4th. Perhaps you could have a bash at some good practical definitions of the terms used in normalisation - as a kind of 'demistification' level zero article. I'm sure there is something simple I'm not getting in normalisation, however here are my 'simple' definitions (which may be wrong)
Attribute: This is any piece of data. In 1NF equates to a column
Attribute Key: a piece of data that on its own, or when combined with other attributes could uniquely identify a row.
Candidate Key: any column, or combination of columns in 1NF that would uniquely identify a Row
Primary Attribute Key: A single column candidate key
Elementary Attribute Key: ~ still unsure about this one.
