Oracle works by default with row level locking.
This is the most low level locking exists.

Oracle has got inbuilt locking feature as it is supporintg multiuser environment. If user a select a table for updation user b can still view the information but he cannot see the changes made by user a unless user a commits it. Same way if user b updates anything in the table these changes will take effect only once user b will commit the changes. This is like read consistency in oracle.
