Answer Posted / saravankumar
A transaction is a unit of work in which a series of
operations occur between the BEGIN TRANSACTION and END
TRANSACTION statements of an application. A transaction
executes exactly once and is atomic ?
all the work is done or none of it is.
Operations associated with a transaction usually share a
common intent and are interdependent.
By performing only a subset of these operations, the system
could compromise the overall intent of the
transaction. Atomicity eliminates the chance of processing a
subset of operations.
