# What is a Clustered Index?

The data rows are stored in order based on the clustered index key.

Data stored is in a sequence of the index.

In a clustered index, the physical order of the rows in the table is the same as the logical (indexed) order of the key values.

A table can contain only one clustered index.

A clustered index usually provides faster access to data than does a non-clustered index.
