In database design, how do you handle recursive relationships between entities?

Create a new database for each recursive relationship
Ignore recursive relationships in database design
Use a foreign key in the same table to establish the relationship
Use a separate table to represent the recursive relationship

In handling recursive relationships in database design, you typically use a foreign key within the same table to establish the relationship. This involves referencing the primary key of the same table, allowing an entity to be related to itself. It's a common technique for modeling hierarchical structures.
