A question about JPA Cascade and removing entity

Question

I have two entities called User and UserProfile in my data model. Here is how they are mapped.

Code from User Entity:

@OneToOne(cascade=CascadeType.ALL)
@P         


        

Answer 1

That is correct when you have a bi-directional relationship the owner dictates the cascade rules since it is the "owner". The "owned" entity essentially follows orders, it can't give the orders -- so to speak.
