I'm building a new db which tracks personnel (one table) and training events (second table). I've created an intermediary table which records which personnel have attended which training events. I'm having trouble figuring out how to build the relationships between these three tables. The key for Personnel is the last four of an individual's SSN. The key for Training is an event code. Both fields have been added to the Tracking table, along with a completion date.
One individual may attend multiple training events. Each training event may be attended by multiple people. Each individual may attend multiple training events on the same day. So I think this equates to:
Personnel - Tracking: one to many
Tracking - Training: many to many
Is this correct?
When I try to build the relationships, it always turns out as a one to one relationship, and I can't figure out how to change this. I'm using Access 2007, and it's been about 10yrs since I've built a db, so I'm learning from scratch.
