Entity Relationship

[Awanish Kumar]

Good Morning Everybody

I am Awanish Kumar and I want to ask some doubts.

1- Without Foreign key how we can relate one entity to another entity?
2- What is Recursive Relationship? And also I need example?

So please have the solution, provide me.

Thanks
Awanish Kumar
