WebBoyce-Codd normal form is considered to be a strong variation of 3NF. A table R is in Boyce-Codd normal form (BCNF) if for every nontrivial FD X ->A, X is a superkey. BCNF is a stronger form of normalization than 3NF because it eliminates the second condition for 3NF, which allowed the right side of the FD to be a prime attribute. Thus, every ... WebTo learn about BCNF in detail with a very easy to understand example, head to Boye-Codd Normal Form tutorial. Fourth Normal Form (4NF) A table is said to be in the Fourth Normal Form when, It is in the Boyce-Codd Normal Form. And, it doesn't have Multi-Valued Dependency. Here is the Fourth Normal Form tutorial. But we suggest you to understand ...

It is visually recognizable by the existance of "Attributive entities" in the data model, for things like Types (e.g. roles, status, process state, location-type, phone-type, etc). The attributive entities (sub-subtypes) are lists of finite sets of values that further categorize a class level entity. totojitu 8888
