"An atomic transaction [has] two properties: recoverability and serializability. Recoverability means that the transaction completes or fails entirely. Serializability means that the transactions exhibit behaviour consistent with some total ordering. A serial transaction is a transaction that only provides serializability."
What they call recoverability4.4 is what I call atomicity, and serializability is a way to provide isolation in the sense that transactions do not intervene with other transactions performing conflicting file operations (which is the total ordering they mention). So in fact STs are (to some extent at least) IOTs!
