Q$2$: Translate the following ER diagram into relational schema and write the SQL DDL commands to create the resulting

relations. Identify any constraints which are in the ER diagram, but you are not able to capture when creating the

relations, in a brief paragraph. If you had more than one option in how to convert an object, briefly explain why you

chose the implementation which you did.

This model represents part of a set of historical records, documenting the endless cycle of war.

$($Friendly reminder: by SQL DDL commands, we're basically talking about the CREATE TABLE stuff$)$
