The default transaction isolation level in Oracle Database is Read Committed. This means that a transaction can only see data that has been committed by other transactions. This offers a good balance between consistency and concurrency, allowing multiple transactions to access data simultaneously without risking data inconsistencies. However, it may lead to non-repeatable reads, where a transaction sees different values for the same row if it is updated by another transaction during the first transaction's execution.
