WebBoyce-Codd Normal Form (BCNF) (cont.) • Ideally, relational database design should strive to achieve BCNF or 3NF for every relation schema. Achieving the normalization status of just 1NF or 2NF is not considered adequate, since both were developed historically to be intermediate normal forms as stepping stones to 3NF and BCNF.

WebThird normal form (3NF) is a database schema design approach for relational databases which uses normalizing principles to reduce the duplication of data, avoid data … WebIn other words BCNF requires that every nontrivial determinant is a superkey even its dependent attributes happen to be part of a key. A relation, R, is in BCNF iff for every nontrivial FD (X->A) satisfied by R the following condition is true: (a) X is a superkey for R BCNF is therefore more strict. rbc credit card world elite https://boudrotrodgers.com
