Currently the relation only consists of a start time, and it is believed to last 1 hour. The addition of a M:N relationship means that a single event can have multiple timeslots, and thus we can now imply how long the event takes and thus satisfy the new criteria. It also allows for simultaneous events, which is also a good thing. Currently the relation only consists of a start time, and it is believed to last 1 hour. The addition of a 1:N relationship means that a single event can have multiple timeslots, and thus we can now imply how long the event takes and thus satisfy the new criteria. It however stops more than one event happening at the same time, which would severly weaken the timetable. Currently the relation only consists of a start time, and it is believed to last 1 hour. By adding a duration in minutes, we can now imply how long the event takes and thus satisfy the new criteria. Currently the relation only consists of a start time, and it is believed to last 1 hour. By adding a duration in hours, we can now imply how long the event takes and thus satisfy the new criteria. This implies that event durations are in multiples of hourlong periods. Currently the relation only consists of a start time, and it is believed to last 1 hour. By adding an end time, we can now imply how long the event takes and thus satisfy the new criteria. A timetable database is required for a University Department. Each taught event is part of a module, each event will have exactly one member of staff associated and several individual students. Each event takes place in a single weekly time slot. Each time slot has a day of the week and a time of day associated. Each of the weekly time slots is exactly one hour long, however we wish to represent the fact that some events take more than one hour. Which of the following does not represent a possible solution.
