Abstract: A reservation system synchronization process that synchronizes scheduling, customer, and configuration information and reduces conflicts for calendar-driven consumer service businesses. The process keeps business calendar information on both a local computer system, residing at the local business facility, and a webserver attached to the Internet, each of which is self-sustaining in the event of a computer system or network connection failure. A polling process synchronizes the reservation information entered into the databases on each computer system. The reservation system synchronization process automatically resolves conflicts and avoids information loss.
