Session 5：Assignment One Question : Think of the small database we used in our lab exercise - Products and Suppliers. Briefly describe how this database observes any two of the four design principles outlined above.

There have two princiles for the relational database, duplicate information, correctness and completeness of information which is very important and can't make any mistakes. Otherwise the general reorts will be contain incorrect information and misinformed.
