3NF or BCNF?
 

hi, is the following table in 3NF and BCNF (boyce codd normal form)?

PL(Team, played, Won, Draws, Lost, goals-scored, goals-against, Points)

I mean, its purpose seems simple enough, but it is confusing to me either whether its possible to decompose it to BCNF.
anyone got any clues??

Every database design with respect to some context and so you should let us know what you are trying to store in the tabled and what each column is all about.

Well, the purpose of the database is to store information on a football,soccer league, stating the facts and figures about the teams. For example dta would be updated accordingly for if a team would play a game and score 2 goals, the played column would increase 1 and the goals would increase by 2. Sorry for my bad description, heres a table .

Team, played, Won, Draws, Lost, goals-scored, goals-against, Points
England, 8, 7, 1, 0, 19, 6, 22
Brazil, 9, 6, 2, 1, 11, 2, 20

hope my question is abit clearer.

Read the welcome email and it says when you can edit your own posts and its after 25 posts.

Now about your query. I think your table structure is in 3 NF provided your team is the unique key.
