They have to be store only in disk and the memoryreleased. But when an isolated query is requested against these tables they haveto be uploaded again in main memory. In order to avoid this time expensiveand inefficient situation it is propose within this project a clever way to storethe table in disk. Then when a query is requested with the help of a bufferand a reduced amount of IO operations the complete query is performed anduploading the full table in main memory is avoided.+-

Although we ask readers to do a lot of computing, we don’t provide very many formulas in this chapter, or throughout the book for that matter.
This is deliberate.
It helps us stress two things: • There are few -classical situations- for which specific formulas will always be applicable.
Each new problem calls for examining the factors involved, considering which are most important, and basing our computation on the interactions among these factors. • We believe students learn to understand concepts much better when they have to invent their own formulas.
In real life, back-of-the-envelope problem solving is much more common, and much more likely to give the kinds of insights that are sought, than the use of formulas from a textbook, even our textbook.” Michael J.
