Problem 1 (14 Points) Answer Yes or No to the following Functional Dependency questions. Base your answers on the data shown in Table X below. There are no further rows in this table. Provide reasoning VERY briefly.


a1 b1 c1 d1 2013
a1 b1 c2   2013
a2 b2 c1 d1 2014
a3 b2 c2   2014
a3 b3 c1 d1 2014
a5 b3 c2   2014


1). Does A→B?

2). Does B→A?

3) Does B→E?

Hint: consider null value as a regular value.


4).Does E→B?

5). Does C→D?

6). Does E→D

7). Does A+C→D?



Problem 2 (5 Points): Table “Complaints” records complaints related information. Given the functional dependencies identified below, identify the primary key. Do not assume any further functional dependencies.

Complaints: (Complaint#, ComplaintReason, CustID, CustName, CustAddress, ReviewDept, AffiliateSite)

All Functional Dependencies:

Complaint# ComplaintReason

CustID CustName, CustAddress

ComplaintReason ReviewDept


Problem 3 (5 Points): Normalize the following table into first normal form. The table uses one row to record information about each student. A student may take one or more electives. This table is not in 1NF. Normalize this table so it is in 1NF. In your answer, list all columns of the new table, the primary key, and all data, in a table format.

SID LName FName Electives
100345 Ford George Geometry, Dance
200898 Gibbs Mary Orchestra
300987 Jordan Jeff Orchestra, Creative Writing, Dance


Problem 4 (20 Points): Determine if each of the following tables satisfies 2NF. If the table is already in 2NF, say so. If the table violates 2NF, say so and produce the normalized tables. Briefly describe the normalization process. Please see solutions document to the exercises. Be sure to identify the primary key for each table you write. The primary key and additional functional dependencies are already identified.

Additional FDs: Event# Date, OrganizerName


B: FileDownload: (SessionId, DownLoadId, FileName, SessionStDateTime, SessionEndDateTime)

C. Sale: (DateCustomer#Product#, Vendor#, Vendor-City)

Additional FD: Vendor#Vendor-City


D. BookInfo: (BookTitle, DateofPrint, #copiesPrinted, #copiesSold, Price, MajorSponsorName)

Additional FD: TutorId#TutorFName, TutorLName, TutorAffiliation

StudentIdSFName, SLName




Problem 5 (6 Points): Normalize the following table into 2NF and display the final tables with data in them. Take the primary key and functional dependencies as given. Do not assume further funtional dependencies.
