Hi there
I have a relational model that I need to normalise to check there will
be no update anomalies and get it to Boyce Codd normal form.
Could some please help me fully understand the concept of a functional
dependency?
I dont quite understand how to approach converting my relational model into
BCNF.
Do I just assume the funtional depndancies based on what the context of the
overall system is or is there a way to correctly go through each relation
and check for FD's?
I undertsand FD's to some degree and the purpose of normlisations but im a
little vague on how to get started
If there is can some one help me to understand one of my relations below? I
really want to understand the process.
relation name:VENUE
CK VenueID
(VenueID,NameOfVenue, Address, Telephone ,EntryCost ,OpenTime
,CloseTime,Website,VenueBudget)
relation name: TRACK
CK AlbumId
(AlbumId,TrackNumber,TrackName,Length,Review,PersonId)
