Using Microsoft® .NET connected software, Dollar Rent A Car created an XML Web services interface to expose its existing mainframe-based reservation system for access by existing and potential business partners. So far, this capability has resulted in millions of additional rate requests, thousands of new reservations, millions of dollars in additional revenue and significant transaction fee savings. It also provided a re-usable link Dollar has used four additional times, extending the functionality of its legacy systems to capitalize on new opportunities ahead of the competition.
