Part 1) 55%
Complete Review Question 17.5 on page 509 in the Connolly text; explain each constraint (40%) and provide an example of each constraint other than the one in the text (15%). The response should be 500+ words
Part 2 a) 10%
Background
We want to keep track of the price we charge for each type of part, the supplier for each type of part, and the amount we pay the supplier for each type of part (the cost). Each supplier can provide us with many different types of parts, but each part can be provided to us by only one supplier. This requires a one-to-many relationship.

Functional analysis:
Part —- > Price, Cost, Supplier, Street, City, State, Zip, Telephone
Supplier —- > Street, City, State, Zip, Telephone
Part —- > Price, Cost, Supplier
Table:
Parts (Part, Price, Cost, Supplier, Street, City, State, Zip, Telephone)
Compete the following:
1. Copy and paste the 2NF definition from the Connolly text (see page 422) 2%
2. Is the above table in 2NF? 3%
3. Using the table and field names in the above table explain your answer in plain English. 5%
Part 2 b) 10%
Background
We want to keep track of the price we charge for each type of part, the supplier for each type of part, and the amount we pay each supplier for each type of part (the cost). This time, a supplier can provide us with many different types of parts, AND each part can be provided to us by more than one supplier. Each supplier may charge us a different amount for each part (cost). This requires a many-to-many relationship.

Functional analysis:
Part —- > Price
Supplier —- > Street, City, State, Zip, Telephone
Part, Supplier —- > Cost
Table:
Parts (Part, Price, Cost, Supplier, Street, City, State, Zip, Telephone)
Complete the following:
1. Copy and paste the 2NF definition from the Connolly text (see page 422) 2%
2. Is the above table in 2NF? 3%
3. Using the table and field names in the above table explain your answer in plain English. 5%
