Oh, interesting! I was a Sr. Software consultant for Starwood back in the day. They had an interesting, grandfathered, tax scheme that allowed for insane growth. Anyway, I wrote the Sales Management and Revenue Tracking System (their name, I pushed for Revenue Tracking For Management) that helped them to prioritize and track rates across all their properties in the mid-90s.

Got close to pushing them to a centralized database (instead of the per-property Access database), but left before we could finalize that project. Ugh, and the reports I had to design... they wanted smaller than 7 point font on legal paper that would then be faxed. Every property would fax quarterly reports generated by my software for board review.

Interesting times.
