With all due respect, neither I nor Alfredo owe you or anyone else an elementary education in the fundamentals of your practice. You, on the other hand, have a responsibility to educate yourself in those fundamentals.

Your remarks betray ignorance of data management fundamentals and a profound confusion between the logical and the physical. A physical pointer is perfectly appropriate at the physical level provided no user ever interacts with it directly at the logical level.

In your case: Very sound advice.

ODBMS is not a new design and has eclipsed nothing. Only an ignoramus such as yourself could fail to recognize those facts.

Since you base your conclusions on ignorance, I fail to see why anyone should care what you think.

Fuck you, you lazy, ignorant freeloader. I paid for my education. Go pay for your own.
