Clustered Index:- It reorder the table phyically and stores
data in a DATA PAGE. DATA PAGE is nothing but page contains
all the data in correct order.Indexing is known as index in
a book(titles with page number).It helps the SQL SERVER to
retrive the data quickly and make the query to perform
fastly.Only 1 index for a table.
Non Clustered Index:- Index that is created in any order.
we can create up to 249 in a table.Indexing is known as
index in a book(titles with page number). performance will
be little bit less than the clustered index.
