If the dates are different in TABLE_1 and TABLE_2 you will have to join both tables on their rank. For exemple.
Is it not just the case of joining on the date and comparing the IDs are the same. This assumes that table_1 is the master sequence.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
