your question is not clear. you are asking about development point of view? or you asking about business rules. so i am answering you in business rules perspective. Hope these rules help you to find out your business needs. These points are common which used in almost every time table management system. In which format you store Time? is this application for single country if yes then okay otherwise you need to store time in UTC. User Rights who can edit and manage Time Table? How you inform your user if his/her timetable updated by admin? How you enter data in system from given sheets? want to swap time slots of users? then how your UI behave in real time? Leave management effect your timetable ? you want to calculate salary on the base of timetable hours?
