Sys equivalent of query submission INFORMATION_SCHEMA

Question

I wanted to get a list of all cascading deletes in my database, so I used the INFORMATION_SCHEMA view:

 SELECT * FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS WHERE DELETE_RULE = 'CASCADE' 

What is the equivalent of this query using sys system views?

Answer 1

 SELECT * FROM sys.foreign_keys WHERE delete_referential_action = 1
