Lab 3: Normalization
Assignment: Problem #11 from Chapter #6.
(Be sure to note that this is PROBLEM and not REVIEW QUESTION).
Normalize a set of data to 1st, 2nd and 3rd normal form by creating relational schemas, dependency diagrams and an Entity Relationship Diagram (crow’s foot notation).
For this lab, complete problem #11 in Chapter 6. Be sure to complete each letter (a thru c) for the problem. The ERD for letter cmust be completed with the use of Microsoft Visio.
Remember to include headers on all documents you submit to include a brief descriptive title, your name and a date.
Question 11:
Given the sample records in the CHARTER table shown in Table P6.11, do the following:
-
Write the relational schema and draw the dependency diagram for the table structure. Make sure that you label all dependencies. CHAR_PAX indicates the number of passengers carried. The CHAR_MILES entry is based on round-trip miles, including pickup points. (Hint: Look at the data values to determine the nature of the relationships. For example, note that employee Melton has flown two charter trips as pilot and one trip as copilot.)
-
Decompose the dependency diagram you drew to solve Problem 11a to create table structures that are in 3NF and write the relational schema.
-
Draw the Crow’s Foot ERD to reflect the properly decomposed dependency dia- grams you created in Problem 11b. Make sure the ERD yields a
database that can track all of the data shown in Problem 11. Show all entities, relationships, connectivities, optionalities, and cardinalities.
