Assignment Help:

In problems 1 - 4, you are given the columns of a table, and a set of functional dependencies.  Determine the normal form of this table.  Remember that the normal form is the HIGHEST normal form for the table (e.g. if a table is in both 1st NF and 2nd NF, then what you report is 2nd NF).  Always start by identifying the candidate keys.
