::The assignment specifies we include "validfrom" and "validto" dates. This implies that we could have several schedules for each student/teacher. eg. one for summer, another for fall, etc. However, this being our first assignment I think it would be reasonable to have exactly one timetable per student/teacher. We would then use the "validfrom" and "validto" dates to tell us when the schedule has become outdated.... John
2.# I did not understand the previous question, therefore the answer was not very useful for me. Can you explain why we would consider specified above relationship schedule and student/teacher? Isn't the schedule is created dynamically by fetching the data form the tables in data base? -- Natalia
