Surging Rodent blogs about interpreting the ER Diagram in ER Exercise Number 3. The saga continues.
The simple answer is “yes”, you can interpret relationships between entities by more than one route if there is more than one route in the relationships connecting them. Here's Rodent's full quote for you to consider:
When I work on the ER diagram exercise 3, is there more than one way to determine the information of "section". In class, we deteremine the value of "section" by: "dept" -> "offered" -> "course" -> "section". My question is: could we start from "dept" -> "major" -> "student" -> "enroll" -> "section"? because it looks like more than one way connected between "Section" and "Dept"
