I'm not looking for extra work at all. I've just enumerated the data types that we, as students, should support on the solution. Anyway, I will implement everything with sequential access files because it's the easiest way to do it. Then I can optimize it if I want by creating caches in the middle.
I will use algorithms like Natural Selection, and Merge algorithms to implement the operators. I know this will be very slow, but this is the easier way. What you think?

No. Moreover, the class I'm taking now is the correlative with the Databases class. That's why I'm asking here... I have to learn it for myself.

thanks for your help
