ANN.2

CSE4701

Problem 15.29 6th ed

Consider the table:Orders (O#,I#,Odate, Cust#, Total_amount, Qty_ordered, Total_price, Discount%)

What are the Functional Dependencies?:

Is it in 2 NF ?

O# Odate Cust# Total_amt

O# I# Qty_ordered Total_price Discount%

No! Odate, Cust#, Total_amt Partially Dependent on only Part of Key O# I# namely O#

ANN.3

CSE4701


How do you Fix the Single Orders Table?

Is it in 3NF? Yes – No transitive functional

dependencies XY and Y Z , with X as the Primary Key, where Y is not a candidate key

Create Two Tables Order (O#,Odate, Cust#, Total_amount)OrderedItem (O#,I#, Qty_ordered, Total_price, Discount%)

ANN.4

CSE4701


Consider the table:CAR_SALE( Car# , Date_sold, Salesman#, Commision%, Discount_amt)

Assumptions Car can be sold by Multiple Salepersons Thus, Primary Key: Car# , Salesman# w/ FDs

Car# Date_sold Car# Discount_amt Car# Salesman# Salesman# Commission%

Is it in 2NF?

No! Car# Date_sold and Car# Discount_amt are not FFD on Primary Key – since Depend on Only Part

ANN.5

CSE4701

Problem 15.30

How Do you Convert to 2NF? Recall FDs

Split into Three Tables

CAR1( Car# , Date_sold, Discount_amt)CAR2( Car# , Salesman#)CAR3(Salesman#, Commision%)

Car# Date_soldCar# Discount_amtCar# Salesman# Salesman# Commission%

ANN.6

CSE4701


Consider the table:TreatPatient (Doctor#, Patient#, Date, Diagnosis, Treat_code, Charge)

Assumptions and FDs Patient Treated by Physician on Date with a Diagnosis,

Treatment Code, and Charge Every Treatment Code has a Charge {Doctor#, Patient#, Date}{Diagnosis, Treat_code, Charge} {Treat_code}{Charge}

Is it in 3NF?

No - Convert

ANN.7

CSE4701

Problem 15.33

What do you look for? Transitivity What is the Problem?

TreatPatient (Doctor#, Patient#, Date, Diagnosis, Treat_code)

BillingAmount(Treat_code, Charge)

Charge a non-Key Attribute is Dependent on Treat Code another non-Key Attribute

Split into Two Tables FDs Now are Fine

ANN.8

CSE4701

Problem 15.35

Given Table Below - What is Candidate Key? BOOK (Book_Name, Author, Edition, Year)

Book_Name, Author, Edition Why? Sometimes Edition Issues Twice in 1 Year

What is the main FD? Book_Name, Edition Year

Is it in 2NF? No: Since Year Dependent on only Part of Key

Convert:

BOOK (Book_Name, Author, Edition)BOOK_YEAR (Book_Name, Edition, Year)

ANN.9

CSE4701

Problem 15.35

What are the Multi-Valued Dependencies?

How Do You Separate the Dependencies

BOOK(Book_Name, Author, Edition)BOOK_YEAR(Book_Name, Edition,Year)

Book_Name AuthorBook_Name Edition.

SPLIT INTO THREE TABLES

BOOK (Book_Name, Edition)BOOK_AUTHOR (Book_Name, Edition, Author)BOOK_YEAR (Book_Name, Edition, Year)

Homework Problem 3.2: 3rd, 4th, and 5th Editions: Problem 8.13a, b, and c;

Problem 4.10 from the 6th edition. Use MySQL Workbench Load DBs/SQL Queries

Look at 1st Problem Homework 37.23 3rd or 6.18 4th to 6th

a. How many copies of the Book titled “The last Tribe”Are owned by the library Branch whose name is “Sharpstown”?

What Tables are Needed?• Book and Book_Copies to find

the number of copies of“The Last Tribe” bookJoin on BookID

• Combine the result with theLibrary_Branch table for the“Sharpstown” BranchJoin on BrachID

ANN.28

CSE4701

7.23a 3rd/6.18a How many copies of the Book titled “The last Tribe” Are owned by the library Branch whose name is “Sharpstown”?

Finding “The Last Tribe” book and its copies at each Bracnh

BOOKRES = BOOKCOPIES * (Title=‘The Lost Tribe’

(BOOK))) )

BookId

This gives us a result table linked on BookID for ‘The List Tribe” that has

rows for each library branch that has that book along with No_of_Copies

Finding “Sharpstown” Branch

BRANCHRES = BranchName=‘Sharpstown’

(LIBRARY-BRANCH))

This gives us a result table with the BrachID of ‘Sharpstown”

Combining the results

ANSWER = No_Of_Copies (BRANCHRES * BOOKRES))

BranchId

Single Relational Algebra Statement

No_Of_Copies( (BranchName=‘Sharpstown’ (LIBRARY-BRANCH)) *

(BOOKCOPIES *(Title=‘The Lost Tribe’

(BOOK))) )

BookId

How do we write the SQL Query? What are Joins?

SELECT No_of_Copies

FROM LIBRARY-BRANCH, BOOK, BOOKCOPIES

WHERE BOOK.TITLE = ‘THE LOST TRIBE’ AND

LIBRARY-BRANCH.BRANCHNAME = ‘THE LOST TRIBE’ AND

BOOKCOPIES.BOOKID = BOOK.BOOKID AND

BOOKCOPIES.BRANCHID = LIBRARYBRANCH.BRANCHID

Another HW3 Hint –What about Problem 3.3c?

Find all of print album name and tracks of all of the albums by the composer James Hetfield, grouped by Album

What Does Data for Track Look Like?SELECT NAME, COMPOSER FROM CHINOOK.TRACK;

ANN.31

CSE4701

Another HW3 Hint –What about Problem 3.3c?

There are other Spellings to Consider: J. Hetfield

There are some Hetfields without First Name or Initial

What SQL Command is Needed for Searching Composer? LIKE is Used to Compare Partial Strings '%' (or '*') Replaces an Arbitrary # of characters

'_' replaces a single arbitrary character

SELECT FNAME, LNAMEFROM EMPLOYEEWHERE ADDRESS LIKE '%Houston,TX% '

ANN.32

CSE4701

Another HW3 Hint –What about Problem 3.4b and c?

Count and print the number of suppliers for each of the eight different categories of food which by name are: Beverages, Condiments, Confections, Dairy Products, Grains/Cereals, Meat/Poultry, Produce, Seafood

For each country (ShipCountry in Orders), total the Freight charges. The countries are: France, Germany, Brazil, Belgium, Switzerland, Venezuela, Austria, Mexico, USA, Sweden, Finland, Italy, Spain, UK, Ireland, Portugal, Canada, Denmark, Poland, Norway, Argentina

Consider Requirements for Managing Books Across Multiple Branches of Library

Books and Branches have unique identifiers A book has a title, publisher, and pub date Publishers have names and contact info Authors need to be uniquely identified and associated

with the books that they have written Borrowers need to be uniquely identified and have

unique Library Card numbers and contact info A library has branches each with a unique ID Borrowers take out book loans at a given branch with

the data checked out and date due A library keeps track of all of the books including

potential multiple copies Design an EER diagram
