This week's giveaway is in the Cloud/Virtualization forum. We're giving away four copies of Secure Financial Transactions with Ansible, Terraform, and OpenSCAP and have Lucian Maly on-line! See this thread for details.
Hello, ACID means Atomicity, Consistency, Isolable and Durability. In this case, what is the difference between Atomicity and Isolable? It seems quite similar.
Hi Benson, Atomic means that the entire operation should either succeed or fail. You cannot have part of an atomic operation succeed while another part fails. Isolation deals with how each transaction affects and is affected by other transactions that are occuring. This is where we set the isolation levels on transactions to prevent or allow: dirty reads, non-repeatable reads, and phantom reads. Regards, Andrew
