Many to Many relationships


#1

I would like to add a many to many relation ship between tables.


#2

Hey Lotte, thanks for using dbdiagram! A many-to-many relationship usually requires a table in the middle. E.g:

  • A Book has multiple Authors
  • An Author can write multiple Books
  • That means there should be an Authorship table with (BookID, AuthorID) that indicates these links.

Do you mean to write the diagram without mentioning the Authorship table at all?
