Functional dependencies | Information Systems homework help

Assignment Instructions

Required Reading
1. Pratt – Concepts of Database Management – Chapter 5

Assignment:
Complete the Premiere Products Exercises in Chapter 5 on page 180/181 (exercises 1 & 2). The % after an instruction indicates the % of grade for this exercise.

Include the below numbers and letters to organize the submission – do not include the questions.

1) For Exercise 1
A) Copy the definition of functional dependency (from the text), then explain it in your own words including an example not in the text or this exercise. (5%)

B) Submit one complete set of functional dependencies (use the notation found on the bottom of page 162, ensure all fields are included at least once). (15%)

In your own words and using field names from this exercise, explain one row of functional dependencies (this demonstrates an understanding of how to apply the concept).

C) Submit the 3NF table(s) (use the shorthand table notation found on page 34, and 162). The tables and fields on those pages are similar to those assignment. That is because they are also based on Premier Products example. The main point in referencing those pages and tables is to provide examples of the notation format – there may be similarities in content – but base your submission on fields in the exercise. (15%)

D) For each 3NF table:  
Include a statement, in your own words that explains the primary key selection: why is that field a good choice for the primary key? (10%)<o:p>
