The type of integrity constraint that does not allow someone to create an order for a non-existent customer is a relational integrity constraint. This constraint ensures that the relationships between tables in a database are maintained and that data is not entered that violates these relationships. In this case, the order table would have a foreign key constraint that references the customer table, and would not allow an order to be created for a customer that does not exist in the customer table.
