I user FMDB for all my Project that have heavy usage of "INSERTs" and FMDB is not out of date. The last commit on Github was at last november. If you go with sql I recommend to use FMDB.
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.
