Well, that's the idea that this company calls this field X, but it's named Y in that company. We have to look at the data and figure out what it is and then match it up to the other field in the other spreadsheet. Say that we're looking for first name, or we're looking for a name, and this company has first name, last name, but this one just has it all in one field, and normalization helps. When you normalize it, you build little programs that help you figure out how to split it.
