Data Modeling, Normalization & Optimization
Order Description
1) Based on the feedback received on your Topic 2 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?
3) APA format is not required, but solid academic writing is expected.
4) This assignment uses a grading rubric. Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become
familiar with the assignment criteria and expectations for successful completion of the assignment
