Schedule management system

A schedule management method comprising the steps of:

• preparing a schedule data storage unit for storing the schedule data including the identifier of the owner of a schedule and the time zone, the activity and the reservation state;
• preparing a definition data storage unit for storing definition data which defines whether or not a new reservation registration request from a terminal which provides a request for reserving a schedule is accepted and defines whether or not the schedule is permitted to be displayed in accordance with the reservation state in said schedule data storage unit;
• accepting a request for reserving a schedule, determining whether the registration of said reservation schedule is permitted or not based on the schedule state of the schedule data existing in said schedule data table and said definition data, and in the case where said registration is permitted, registering said reservation schedule representing said owner's response to the schedule data in said schedule data table;
• accepting a schedule approval/disapproval request from the owner of a schedule, and rewriting the schedule state of the corresponding schedule data in said schedule data table;
• accepting a schedule display request, determining whether the schedule existing in said schedule data table is displayed or not to said another client based on the schedule state of the schedule data existing in said schedule data table arid said definition table, and displaying only the schedule data which is determined to be displayed;
• and
• accepting a request for searching for an unoccupied time for said schedule, determining whether the time zone of said schedule is rendered an occupied time based on the schedule state of the schedule data existing in said schedule data storage unit and said definition data, and when said time zone is rendered an occupied time, displaying an unoccupied time by removing the time zone of said schedule from the unoccupied time.

A machine-readable storage medium for storing a program of instructions executable by machine, said program comprising, for schedule management, the steps of:

• upon acceptance of a request for reserving a schedule, determining whether the registration of said reservation schedule is permitted or not, based on a reservation state existing in a schedule data storage unit for storing the schedule data including the identifier of the owner of a schedule, and the time zone, the activity and the state of said schedule, and definition data which defines whether or not a new reservation registration request from a terminal which provides a request for reserving a schedule is accepted and defines whether or not the schedule is permitted to be displayed in accordance with the reservation state representing said owner's response to the schedule data in said schedule data storage unit, and when said registration is permitted, registering said reservation schedule in said schedule data storage unit;
• upon acceptance of a request from the owner of said schedule for approving/disapproving a schedule, rewriting the schedule state of the corresponding schedule data in said schedule data table;
• upon acceptance of a request for displaying said schedule, determining whether said schedule existing is displayed or not to said another client based on the schedule state of the schedule data existing in said schedule data storage unit and said definition table, and displaying only the schedule data determined to be displayed;
• and
• upon acceptance of a request for searching for an unoccupied time for said schedule, determining whether the time zone of said schedule is rendered an occupied time based on the schedule state of the schedule data existing in said schedule data storage unit and said definition data, and when said time zone is rendered an occupied time, displaying an unoccupied time by removing the time zone of said schedule from the unoccupied time.
