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 "Written By". This implies that a book is written 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 "Authored By". This implies that an author from the list of authors may have authored one or more books from the list of books.
These relationships are typically many-to-many relationships, as one author can write multiple books, and one book can be written by multiple authors.
