What's the difference between embedsMany and hasMany in Strongloop loopback

Question

At first sight they seem to do the same thing: define a one-to-many relation So why would you choose one or another?

Answer 1

EmbedsMany - a model that embeds many instances of another model; for example, a Customer can have multiple email addresses and each email address is a complex object that contains label and address. A hasMany relation builds a one-to-many connection with another model.

EmbedsMany embeds all child objects in the same parent object, HasMany stores child objects separately and has a property as the foreign key to reference the declaring model.
