Notes:
This provider had had issues sending over complete datasets before. We should make a note of this when we do future data updates.
When new data files are delivered, new tickers may be added. If new tickers appear in future data updates, we will need to go to D&B and ask them to give us the DUNS numbers for the newly-added tickers.

There is no “matching” in the traditional sense. Instead, we will need to add a column and map the DUNS numbers provided by D&B in the match logic file to the tickers in the data table (e.g. if Ticker = CUBE, then DUNS number = 788617640).
(Note: For the latest self storage dataset, you will not find data for the following tickers: Pvt, REIT, and UHAL. Big Byte Insights stated that these are not part of D&B’s data subscription.)
