Aye Yi Yi. Apparently nobody has a clear understanding of Domain or Tuple Relational Calculus. The thing is, it’s not really calclulus at all. Who knows WHAT it is. OK my guess is that ’tis a screwed up version of Relational Algebra, which seems useless enough to begin with. Enough mumbo jumbo. If you had a hard time understanding this paragraph just imagine my pain trying to figure out what an upside down A means!
In other news.. Hrm, there really is nothing else. Databases are my life for the next few days. Pretty sad eh?
