Normalization is a process involving multiple stages called normal forms that aims to eliminate data redundancy and enhance database design by defining relationships between attributes. While denormalization can compromise normal forms to meet performance needs, higher normalization levels are generally preferred for data integrity. Key concepts include candidate keys, transitive dependencies, and the importance of eliminating repeating groups to ensure each table row defines a single entity.

1. Normalization work as through a series of stages called normal forms Normalization is a
process that is used for changing attributes to entitles. In order to meet performance
requirements you may have to denormalize portions design. Denormalization produces a lower
normal form. Normalization is a very important database design ingredient and the highest level
is always the desirable. A table is in BCNF if every determinant in the table is a candidate key.
A table is in fourth normal form if it is in third normal form and has no independent multivalued
dependencies. Repeating groups must be eliminated by making sure that each row defines a
single entity. It is possible for a table in 2NF to exhibit transitive dependency, where one or
more nonprime attributes functionally determine other nonprime attributes. A determinant is any
attribute whose value determines other values within a column. A dependency of one nonprime
attribute on another nonprime attribute is a partial dependency. Attributes should clearly define
participation, connectivity, and document cardinality. An attribute that is part of a key is known
as a(n) attribute. important nonprime prime entity Data redundancy produces. slower lookups
