I M Having A Hard Time Understanding This Module In My Concepts Of Database Mana

I’m having a hard time understanding this module in my Concepts of Database Management class. The question I need help with is:

Sports Physical Therapy is considering adding doctor information to the database. Determine the functional dependencies that exist in the following table. and then convert this table to an equivalent collection of tables that are in third normal form:

Session (SessionNum, SessionDate, PatientNum, LengthOfSession, TherapistID, TherapyCode, Description, UnitOfTime, DoctorNum, DrLastName, DrFirstName)
