It occurs if the waiting scheme for locked items in unfair, giving priority to some transactions over others.	A situation where two or more transactions are unable to proceed because each is waiting for one of the other to do something.
Starvation is also known as lived lock.	Deadlock is also known as circular waiting.
Avoidance: ->switch priorities so that every thread has a chance to have high priority. -> Use FIFO order among competing request.	Avoidance: ->Acquire locks are predefined order. ->Acquire locks at once before starting.
It means that transaction goes in a state where transaction never progress.	It is a situation where transactions are waiting for each other.
