  Third normal form (3NF) (or fourth normal form, 4NF) is a grouping of data designed to avoid the . anomalies. and . problems. that can occur with data. Data exists in real life as groups of data items. It exists on invoices, weigh bills, tax forms, driving licenses, and so on. These groupings are usually not in a normalized form.

  Fourth Normal Form: A table is in Boyce-Codd normal form (BCNF) and there are no multi-valued dependencies. A multi-valued dependency occurs when, for each value in field A, there is a set of values for field B and a set of values for field C but fields B and C are not related. A Practical Approach . Look for repeated or null values in non-key fields.
