Q. Describe the concept of transaction atomicity?
Answer: A transaction is a sequence of read as well as writes operations upon some data followed by a commit operation. If the sequence of operations in a transaction cannot be completed the transaction must be aborted and the operations that did take place should be rolled back. It is vital that the series of operations in a transaction appear as one indivisible operation to ensure the integrity of the data being updated. or else data could be compromised if operations from two (or more) different transactions were intermixed.
