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). Queries in the strict sense of the word, that is, SELECT statements and other read operations that do not change the database state, are not logged At present, in SQL Server it is only available for natively compiled stored procedures.

Consistent – The saved data cannot violate the integrity of the database. An attribute that cannot be divided further into meaningful subcomponents/sub-attributes is an Atomic attribute.

Transactions are expected to be atomic, consistent, isolated, and durable. • Postgres does not support distributed transactions, so all commands atomic(using=None, savepoint=True, durable=False)¶ Atomicity is the defining property of database transactions. atomic allows us to create a block of code within which the atomicity on the database is guaranteed.
