While I have tried to resist over the years, I realize that I am really a data junky. Not a database junky, but a data junky. I want to know about meaning, about value, about inference. I am especially interested in the temporal aspects of data - recognizing that as circumstances change, so algorithms/rules under which the data were collected might be different. So applying yesterdays derivation/categorization rules to today's data will always be flawed. Future posts will look at the DOW Jones Industrial Average, the need for context in the data/metadata around transactions and other, unusual thoughts around data, capture and use
