Validata Foundations: Why Row Matching Is An Exact Identity Problem

Why Matching Is a Math Problem, Not an Approximation Problem In the previous post, we drew a hard line: data validation means proving two datasets represent the same truth: not approximating it, not sampling it, not eyeballing it. If you accept that definition, a question follows immediately. How do you decide which rows are supposed to match? It sounds like plumbing. It isn’t. It’s the most…
