Finding the rows that differ
It depends on the number of differences, not on the size of the data.
- Differences
- differing items
- Rows
- rows compared
- Hash size
- bytes per hash exchanged
Worked examples, recomputed
Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.
Where it appears
Each mechanism states it in its own names. The general symbol each name stands for is shown with it.
- Data Quality & Validation
How do you check that data is right, when "right" is a claim about the world and not about the bytes?
