Can you demostrate that with your own payroll example? Now you have some runnable procedural/relational code to compare it to: http://www.geocities.com/tablizer/payroll2.htm I'm tired of OOP verbal claims of curing cancer and saving Dolphins.

That link is just the nascent GUI for the payroll system; it's not the payroll system itself. -- Robert C.

Maybe on the weekend. And, I did not see your evidence of "procedural combinatorial explosion" for the library publications example. Do you need to retreive a book to answer that one? Hint: my code implements features, NOT noun taxonomies. If there is mass duplication in feature implementation, then I use subroutine factoring. The DB tracks classifications of specific nouns or kinds of nouns (unless it is trivial and rarely-changing). > ... > > Regards, > Steven Perryman -T- |
