Part 1: Complete review question 17.5 on page 509 in the Connolly text; explain each constraint and provide an example of each constraint. The response should be in the order of 500+ words.

17.5: Describe the purpose of integrity constraints and identify the main types of integrity constraints on a logical data model.

Part 2: 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 only by one supplier. This requires a one-to-many relationship.

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)
