title: what is difference between atomicity and isolation in ACID properties?
body: <p>the difference between atomicity and isolation of DBMS is somewhat vague so i am asking for a clear difference between the two ?</p>
  
  <p>Atomicity and isolation, are ensured in classical database transactions by using a commit protocol. This protocol is used to turn temporary storage into permanent storage - that is, the updates to the transaction's data are not visible until the commit protocol validates the stored data. Note that it is the presence of a commit record in the database log which effectively validates the transaction's data.</p>
