Clustered index Vs Non-Clustered index

Primarily in SQL server there are two types of indexes, clustered index and Non-Clustered index. Let me give you very basic difference between these types of indexes. These two indexes are different in terms how the data is stored. In Clustered index the leaf-nodes contains the data where as in Non-clustered index leaf-nodes contains the bookmarks to the actual data. In other words data is sorted and stored based on the Clustered Index. So that’s the reason you can have only one Clustered index per table.
