You are to show:

1. A 2-D Table with no multivalued attributes  (1NF)Hint: Your table should have 4 rows of data in addition to the column headings.
2. A functional dependencies diagram (see page  217 in your text)
3. A set of relations (tables) with no transitive dependencies (3NF)

•  
  • Note:  If there are no transitive dependencies, then 2NF = 3NF

Suggestion: Copy and paste the text from the invoice below into your table and relations.
