sql statement

/in /by

1) Based on the feedback received on your assignment Database Schema, provide SQL statements to create the (revised) database and populate it with sample data (at least four rows per table).

2) Modify the database by adding an additional column (“Deleted_Date”) to those tables that represent entities that could contain data which can be deleted and justify your rationale in a short paragraph. In addition, explain what the tradeoffs are in using a marker-column for deletion, as opposed to actually deleting a row from a table?

APA format is not required.
