Webb16 mars 2024 · Each rule is called a "normal form." If the first rule is observed, the database is said to be in "first normal form." If the first three rules are observed, the database is considered to be in "third normal form." Although other levels of normalization are possible, third normal form is considered the highest level necessary for most applications. Webb8. Sixth Normal Form (6NF): 6th normal form is not a standardized form but a table eligible for 5NF only can qualify for 6NF. To be in the 6NF a relation should not contain any non-trivial join dependencies. It is stricter and less redundant that DKNF. The relational variables of entities in this form become irreducible components.
