Applied to 1NF this means that a column should not contain more than one value. It should not compose or combine values that have a meaning of their own. In SQL databases transaction atomicity is implemented most frequently using write-ahead logging (meaning that the transaction log entries are written before the actual tables and indexes are updated).
