this is refere to

[Database Scripts] (30pt)

Based on the csns.ddl file generated in the previous exercise, modify the following database scripts:

• db/csns-create.sql - add the SQL statements to create the tables/constraints for the online assignments and submissions.
• db/csns-drop.sql - add the SQL statements to drop the tables/constraints for the online assignments and submissions

at the end of my csns.ddl I have alter table with constraint shoud we create those in our sql-script ? I couldnt understand
