It’s not unusual to have many-to-many relationships in an application. A recent project I worked on had multiple service technicians assigned to multiple locations, for instance. It’s also not unusual for there to be data that applies only to the relationship. In my client’s project, for example, at any location, a service technician has a specific position — and that position can be different from one location to another. (For instance, at one location, the tech might be the "responsible authority"; at another location, the tech might be the "support technician.") In addition, at each location, a tech is assigned a phone extension number where he can be reached.
