This document contains questions for a tutorial on distributed database management systems and normalization. It is divided into three parts. Part A asks students to define the functions of a distributed DBMS and explain the differences between homogeneous and heterogeneous distributed systems. It also asks about transaction transparency. Part B contains questions about determining functional dependencies, converting a table to third normal form, and modifying a table to first normal form. Part C is about keeping a weekly log for assessing a database project.

Tutorial 7
Topic: Distributed database management system and normalization
Objective: Students learn about the Distributed database management system and
apply normalization techniques
Submission: Five minutes before the end of the tutorial word file containing student’s
answers need to be uploaded on Moodle
Part A: Answer the following questions:
1. A fully distributed database management systemmust perform all of the functions of a
centralized database management system(DBMS). What are these functions?
2. Explain the difference between homogeneous and heterogeneous distributed database
management systems (DDBMS).
3. What is transaction transparency? What are some of the basic concepts that one should
know to understand how transactions are managed in a distributed database management
system (DDBMS)?
Part B: Normalization
1.
a. Determine the functional dependenciesthatexistinthe followingtable.
Orders(OrderNum,OrderDate,ItemNum, Description,NumOrdered,
QuotedPrice)
b. Afterdeterminingthe functional dependencies,convertthistable toan equivalent
collectionof tablesthatare inthirdnormal form (3NF).
2. Explainhowwouldyoumodifythistable sothatthe informationwouldbe storedina First
Normal form(1NF) relation?
