Indexes in SQL Server are similar to the indexes in books.
They help SQL Server retrieve
the data quickly.

There are clustered and nonclustered indexes.
A clustered index is a special type of index
that reorders the way in which 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.
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.
