ReadCommitted | Specifies that statements cannot read data that has been modified, but not committed, by other transactions. This prevents dirty reads. | |
Snapshot | Specifies that the data read by any statement in a transaction is transactionally consistent, as if the statements in a transaction receive a snapshot of the committed data as it existed at the start of the transaction. |

Snapshot is data source dependant.
