CIO mentioned rumors on MongoDB superiority (which store data in JSON documents instead of tables) over old relational databases and asked, how do you plan to store data – normalized or not.
Write a paper (up to 2 pages) on relative strengths and weaknesses of relational data modelling in normalized tables for this project. Why do you prefer normalization? Why do you prefer denormalization? Which use cases became possible/impossible/quick/slow due to which properties of both ways?
