A DBMS is inherently less simple than for loops, that's entirely true. But that's the class of problem they were trying to solve. And a DBMS represents vast amounts of energy put into trying to solve that class of problem. So, the problem was a complex one, but one that had many aspects of it already solved, and rather than building on a good solution (the DBMS) they chose to try and reinvent queries. > you should also be aware of the shortcomings of the simple approach Yup, you really can't refuse to learn how databases work. Unfortunately, they didn't know what they didn't know.
