am i a machine?

by selven

Since we are in the test week, i decided its time to learn a few things, while reading some slide, i really started questioning my humanity…. for example:

Operational vs. Declarative Query Languages

  • Operational language specify the objects by means of the way to obtain it.
  • TRC queries just specify the objects
  • Relational algebra queries are typically longer than declarative queries
  • The expressiveness of relational algebra is a subset of TRC, including all safe queries
  • RA is always safe in TRC unsafe queries are possible
  • RA is difficult to write by humans, but easy to evaluate by computers
    <Holy crap, that’s where i start thinking, wtf, I write RA as if it is natural and logical for me, the first time i saw RA i instantly found myself at ease with it.>
  • TRC is easy to write for humans, but difficult to evaluate by computers
    <TRC is easy to write for humans?? Bullshit, after months and months of trying to understand how to write in TRC i still can’t find any logic in using those existential and universal quantifiers>

So am i human or are those ‘rules’ biased? D

Anyways good luck for those who will be having a long test week.

[catching up 15 weeks in 6 hours here :p]
