The DBA asks for your help in planning the data archive (not backup) for the following Sports Physical Therapy database:

Patient Patient Num, LastName, FirstName, Address, City, State, Zipcode, Balance) Session (SessionNum, SessionDate, PatientNum, Lengthof Session, Therapist ID, TherapyCode) Therapies (TherapyCode, Description, UnitofTime) Therapist (TherapistID, LastName, FirstName, Street, City, State, ZipCode)

Determine which data from the database to archive; that is, for each table, specify whether data needs to be archived. If it does, specify which data to archive, when it should be archived, and whether it should be archived with data from another table.
