Question
What do we name the relationship between the listOfAuthors
entity and book
entity and listOfBooks
entity and author
entity in ERD conceptual model?
Solution
In an Entity-Relationship Diagram (ERD) conceptual model, the relationship between the "listOfAuthors" entity and the "book" entity can be named as "Authored By". This indicates that a book is authored by one or more authors from the list of authors.
On the other hand, the relationship between the "listOfBooks" entity and the "author" entity can be named as "Wrote". This indicates that an author from the list of authors wrote one or more books from the list of books.
These relationships are typically many-to-many. A book can have multiple authors, and an author can write multiple books.
