Let's proceed with the normalization process step by step.
Work Example:
Step 1:
Identify and underline all the primary key(s) that contribute fully to the functional
dependence of other attributes.
Select primary keys with unique values to eliminate redundancy and determine other
attributes in the record.
Reserve any other attributes that could potentially become future primary keys as
transitive. Mllustrate the diagram following the sample example.
Note: Steps 1-3 is just for your guideline to produce the final answer diagram and FDs in
Step 4.
Based on sample dummy data, let's assume that
Attribute B is dependent on Attribute A, where Attribute A determines the consistency of
Attribute B values, such as A1B1 and A2B2. Therefore, Attribute A can possibly
be a Primary Key.
Attribute D,E, and F are dependent on Attribute C, where Attribute C determines the
consistency of Attribute D, E, and F values, such as C1 D1, E1, F1 and C2 D2, E2,
F2. Therefore, Attribute C can possibly be a Primary Key.
However, according to the assumption and the following table, Attribute A and Attribute
C cannot be a single Primary Key because A2 and C1 produce repetitive values.
Nevertheless, the combination of Attribute A and Attribute C ensures uniqueness for each
row, such as }{1},AC12, and AC22.
Primary Key: Attribute A and Attribute C
Step 2:
Identify all the related attribute(s) that depend on a part of the primary key, which
contributes partially to functional dependence.
Add the previous diagram from Step 1 as shown in the following sample example.
Step 3:
Identify any related attribute(s) that depend on other non-primary keys, which contribute
to transitive functional dependence. Let's assume Attribute D determines Attribute E.
Add the previous diagram from Step 2 as shown in the following sample example.
Srep 4:
Refer to the diagram from Step 3. Remove any redundancy, following the sample example.
List all the final functional dependencies (FD) and state the type of each.
Note: Please present your final answer in the form of a diagram and list the finctional
dependencies (FDs) as shown in the following example.
FD1: AttributeA, AttributeC AttributeF (FullyPrimary Key)
FD2: AttributeA AttributeB (Partial)
FD3: AttributeC AttributeD, AttributeE (Partial)
FD4: AttributeD AttributeE (Transitive)
Note:
Some cases transitive finctional dependencies may not necessarily exist.
The attribute(s) on the left side of the arrow represents the primary key(s), while the
attribute(s) on the right side should be determined by only ONE value.
For example, in the case of the Matric name, a matric number can determine only ONE
student name, such as 'Ali'. It cannot determine multiple student names, such as both
'Ali' and 'Ahmad'. b. Based on the list of functional dependencies (FDs) in (a), simplify the process of normalizing
the table into 1NF-3NF.
Work Example:
Stepl: INF Table
[Tips: Each row and column must have a single data. Underline all the Primary Key (PK)]
1NF
TableName1
Note: Key attributes are defined, and there are no repeating groups in the table. All attributes
are dependent on the primary key.
Step 2: 2NF Table
[Tips: Break the 1NF table and remove all partial and fully functional dependencies (FDs)]
2NF
i. TableName1(AttributeA, AttributeC, AttributeF)
ii. TableName2(AttributeA, AttributeB)
iii. TableName3(AttributeC, AttributeD, AttributeE)
Tab SECTION B: WORK EXAMPLE PROBLEM-SOLVING
Answer all the questions based on the sample book loan records table provided.
Identify if there is any redundancy in the table above and justify your answer, using your
own simple words based on your understanding.
Answer:
Redundancy contributes to insertion, deletion, and update anomalies. Please provide
examples of each based on the record given in the table, using your own simple words and
understanding.
Answer:
Explain how to eliminate the insertion, deletion, and update anomalies, using your own
simple words based on your understanding.
