What is normalization and types of normalization?
Answer Posted / 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)
