When creating the connections between two classes in UML (using MDriven), I inserted the correct values in each end (e.g. 0..*). However, when pressing Enter, an (e) appeared after the values. I found out, that it stands for "embed".

Which end of the connection should be "embed" in certain situations and why?

Embed is best explained as "in which table is the foreign key placed" This is often self-evident:

  • One-to-Many - foreign key will go in many end.
  • Many-to-Many - foreign key will go into link-class(possibly implicit)
  • One-to-One - This is where Embed-flag becomes important, because it is optional where to put the foreign key.

If you do not know what end to pick - you can just pick any of them. But as you grow more experienced you might want to have the ability to control this.
