Need suggestion for database regarding Stackoverflow related project?

A litte more information would help giving you directions. What data volume do you expect? How many concurrent users will query the database?

Do you plan to store all the questions in the database or just relate to them by ID:s?

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.
