Are the various relationship types defined in detail anywhere?
Also - is it possible to create a relationship to an object 2 levels down? e.g., an object related via LookUp to an object that is related via LookUp?
Master Object = Course
Child Object = Application (has a LookUp to Course and LookUp to Contact)
From the Course I need data from the Contact on each Application
Guessing that I probably have to have cross-object formula fields to bring the Contact data onto the Application - yes?
