Clustered vs Non-clustered Indexes

Question

Hi!!

What is the difference between clustered and non - clustered indexes?

Answer 1

Clustered indexes - The indexes according to which data is physically stored on disk. Therefore, only one clustered index can be created on a given database table.
Non-clustered indexes - These indexes don’t define the physical ordering of data, but logical ordering. Typically, a tree is created whose leaf point to disk records.
