ELECTRONIC CALENDAR WITH GROUP SCHEDULING AND ASYNCHRONOUS FAN OUT METHOD

A system for scheduling time intervals for a plurality of users comprises a database, associated with one or more server means, for storing a profile for potential invitees of the system, the invitee profiles comprising user profiles wherein each user profile comprises information regarding available and unavailable times for that user. A remote workstation comprises a request generating system that is connected over a network to the server means and that generates a request for allocation of a time interval for one or more of the plurality of invitees. At the server, a busy time determination system gathers the profiles for the one or more requested invitees using asynchronous fan out requests to the one or more databases storing the profiles and determines whether those invitees are available during the requested time interval.
