This is a request for help in creating an ERD structure for an Access database.

I've found myself in a commitment to develop a scheduling database. By scheduling, I mean this: There are Stores and there are Merchandisers who must stock the shelves at the Stores on scheduled days during the week. I need to be able to efficiently store data about the stores and merchandisers and be able to print reports of the schedules on a week by week basis (mon-sun), showing which merchandiser works on which days, AND at what time of day (morning,afternoon,evening) the work. Additionally, i need to print daily schedules for each merchandiser, showing all the stores they are to visit. I have constructed two models; which of these is better, or is there a better model?

Store with foreign key (FK) in Week
Week with FK in Weekday (mon-sun)
Weekday with FK in Timeofday (morning,afternoon,evening, +more)
Merchandiser with FK in Timeofday

Week with FK in Weekly Schedule
Store with FK in Weekly Schedule
Merchandiser with FK in Weekly Schedule
Weekly Schedule includes fields Mon-Sun, each denoting an enumeration of timeofday

Please, any suggestions?
