Match each normal form with its primary concern. 1NF A. Eliminate transitive dependencies (i.e. non-key columns cannot be functionally dependent 2NF on another non-key column in the same table) 3NF B. A "Key-value" store (only one non-key column, often to track temporal history of that value) (e.g. {truckID, date, time} -> {GPS_location}) 4NF C. Any further decomposition would lose information (e.g. by breaking apart composite keys) 5NF D. Eliminate mulit-valued attributes (i.e. each cell must contain a single scalar value) 6NF E. Each multi-valued attribute of an entity should have its own "list" table (e.g. a student may have 2 email addresses and 3 phone numbers) F. Eliminate partial dependencies (i.e. all non-key columns must be functionally dependent on the entire composite primary key)
