Each Transaction can occur as though they were occurring one by one, even though they’re actually occurring simultaneously
Ensures that data is managed between database operations so it is not used in Transaction simultaneously. Instead, the first transaction will complete, and then the next will begin
Durable
Permanently preserves all Transaction by saving to permanent storage, not kept in volatile memory
Ensures changes to data made by successfully executed Transaction will be saved, even in the event of system failure (like power loss)
