A clustered index is a special type of index that reorders the way records in the table are physically stored. Therefore table can have only one clustered index. The leaf nodes of a clustered index contain the data pages. Clustered index will be created by default when u create primary key on a column. clustered index is stored in
serial passion.


A nonclustered index is a special type of index in which the logical order of the index does not match the physical stored order of the rows on disk. The leaf node of a
nonclustered index does not consist of the data pages. Instead, the leaf nodes contain index rows. Non clustered index will be created automatically when u create unique key on a column. A table can have no.of unique keys, so we can create no.of non clustered indexes
per table.
