Transaction must be
A - Atomic (it is one unit of work and does not dependent on
previous and following transactions),

C - Consistent (data is either committed or roll back, no
"in-between" case where something has been updated and
something hasn?t),

I - Isolated (no transaction sees the intermediate results
of the current transaction),

D - Durable (the values persist if the data had been
committed even if the system crashes right after).
