database structure is suitable for general purpose qureying
and free from certain undesirable character that lead to
loss of data integrity.

Answer / sripathi venkata ramesh

I am Sripathi Venkata Ramesh from Gudivada and the answer
is mentioned below

Normalization: The focus of normalization is to help data
base designers to design the table structures for an
application. It helps to reduce rebundant table data to the
very minimum. Main use is to improve the performance of
DBMS.


First normal form: There must be no any duplicate
records & repeating groups.

Second normal form: Remove subsets of data and place
in a separate table.

Third normal form: Remove columns that are not
dependent on primary key

Answer / pradeep

normliztion is reduce the complicitty of form,

Answer / srabani das

The basic facts of normalization is to reduced redundancy
which means that information stored only once.storing the
information in several times leads to lost of storage space
and increase in total size of data base.Relation are
normalized so that when relation of database are to be alter
during the life time of the data base. we do not lost
information.

Answer / jasmine

Normalization is a process of designing the table(relation)
with the reduced redundancy and making clear whether the
attributes in a table is depend on the primary key or
dependencies make sense(ie:storing only the related datas
ito the table). This is achieved by normal forms.
Basic types of normal forms are,
1NF-first normal form(Eliminates duplicate or
repeating values)

2NF-second normal form(Eliminates redundant datas in
one or more tables)

3NF-Third normal form(Removing the columns that are
not truely depending on the primary key)

Normalisation is basically avoid redundent data in database
for saving memory space and faster manipulation of data
keep and insert ,update , delete anamollies.....

Answer / r.arjunarao

Normalization means reduces redundancy unnecessary
repetition of data is NF
UnNormalization means intentional introduction redundancy to
a table to improve the performance is De-NF or Un-NF
1NF Any multiple values Attribute have been removed.
2NF Any partial functionality dependency have been removed.
3NF Any transitive functionality dependency have been removed.
4NF Any multi-values dependency have been removed.
5NF Any remaing anomalies have been removed.
