What is the correct name for the relationship properties in the model?

Question

Database design

In the database model design tools, there are different names everywhere. I can't figure out why and how?
Also, somewhere there is an identify setting, somewhere not - what does this mean, in which standard is it described?

As an example:
Visual paradigm -- Relationship


Navicat -- Foreign key


Vertabelo -- Reference
