All of them talk about working backwards, i.e., first now what type of queries you are going to make and select a right data model which can support those queries efficiently. But one thing I cannot understand: You can expect me that I can know some queries that I will be making but how can I know what all queries will be made before hand? I have to remodel the whole stuff when I get a query which I had not thought off?
