Worked examples

Data mapping examples: real runs, published unedited

Each page below is one real source-to-target mapping run over two public vendor specifications: every mapping it proposed with its type and confidence, every question it refused to proceed without, and an honest count of the fields it declined to guess. Nothing is cleaned up: the honest way to judge a mapping tool is its unedited output.

Every page here is output, not explanation — the how-and-why of the document these runs produce lives in the data mapping guides.

The gaps and questions stay on these pages because they are the product’s honest output, not a failure to hide — a wrong mapping is worse than an honest gap. And when an example is re-run, its page is re-read from the new output; the numbers are never carried over.

The layout these runs export ships as a free data mapping template, and the full walkthrough of what belongs in each column is how to create a data mapping document.
