Could you please explain to me the significance of Boyce-Codd Normal Form (BCNF)? I understand what it is and what it does, but not sure if it is that significant. Thank you very much.
Boyce-Codd Normal Form (BCNF) is simply an extension of third normal form (3NF). I did an Ask The Expert response for this term (2001-05-01) that covers it in more detail.
Using present development languages, BCNF is not particularly significant. There were once very good reasons to use BCNF, roughly twenty years ago to exploit the features of DB2 as it existed at that time, mainly from COBOL but also from other mainframe languages.
