WGU Data Management – Foundations Exam Sample Questions (Q59-Q64):
NEW QUESTION # 59
What is a common error made while inserting an automatically incrementing primary key?
Answer: C
Explanation:
In databases, primary keys are oftenset to auto-incrementso that new rows automatically receive unique values. However,one common error is manually inserting a value into an auto-incremented primary key column, whichoverrides the automatic numberingand may cause conflicts.
Example of Auto-Increment Setup:
sql
CREATE TABLE Users (
UserID INT AUTO_INCREMENT PRIMARY KEY,
Username VARCHAR(50)
);
Incorrect Insert (Error-Prone Approach):
sql
INSERT INTO Users (UserID, Username) VALUES (100, 'Alice');
* Thismanually overrides the auto-increment, which can lead toduplicate key errors.
Correct Insert (Avoiding Errors):
sql
INSERT INTO Users (Username) VALUES ('Alice');
* Thedatabase assigns UserID automatically, preventing conflicts.
Why Other Options Are Incorrect:
* Option B (Failing to set a numeric value) (Incorrect):The databaseautomatically assignsvalues when AUTO_INCREMENT is used.
* Option C (Designating multiple primary keys) (Incorrect):Whileincorrect, most databases will prevent this at creation time.
* Option D (Forgetting to specify which is the auto-increment column) (Incorrect):If AUTO_INCREMENT is set, the database handles numbering automatically.
Thus, the most common error isInserting a value and overriding auto-increment, which can cause duplicate key errors and data inconsistencies.
NEW QUESTION # 60
What does the aggregate function do?
Answer: C
Explanation:
Anaggregate functionperforms acalculation over multiple rowsand returns asingle value. Examples include SUM(), AVG(), MAX(), MIN(), and COUNT()in SQL.
* Option A (Correct):Aggregate functions compute values over aset of rows, like summingtotal sales or averaging grades.
* Option B (Incorrect):Selecting rows that appear in one table but not another is done usingset operations (EXCEPT or MINUS in SQL).
* Option C (Incorrect):Eliminating columns is done using thePROJECToperation orSELECT with specific columns.
* Option D (Incorrect):Combining rows from two tables refers to aJOIN operation, not aggregation.
NEW QUESTION # 61
Which clause or statement in a CREATE statement ensures a certain range of data?
Answer: C
Explanation:
TheCHECKconstraint is used in SQL toenforce ruleson a column's values. It ensures that data inserted into a table meets specified conditions, such as range restrictions or logical rules.
Example Usage:
sql
CREATE TABLE Employees (
ID INT PRIMARY KEY,
Name VARCHAR(50),
Salary INT CHECK (Salary BETWEEN 30000 AND 150000)
);
* This constraint ensures thatsalary values fall between 30,000 and 150,000.
* If an INSERT or UPDATE statement tries to set Salary = 20000, itfailsbecause it does notmeet the CHECK condition.
Why Other Options Are Incorrect:
* Option B (FROM) (Incorrect):Used in SELECT statements, not for constraints.
* Option C (WHERE) (Incorrect):Filters rows in queries butdoes not enforce constraints.
* Option D (SET) (Incorrect):Used for updating records (UPDATE table_name SET column = value) butnot for defining constraints.
Thus,CHECK is the correct answer, as it ensures that column values remain within an expected range.
NEW QUESTION # 62
Which relationship or association exists between a supertype and its subtype entities?
Answer: D
Explanation:
Indatabase modeling, the relationship between asupertype and its subtypesis called anIsA relationship.
Example Usage:
* AVehicle supertypemay haveCar and Truck subtypes.
Vehicle
### Car
### Truck
* InER diagrams, this is represented as:
Vehicle (Supertype)
|
### Car (Subtype)
### Truck (Subtype)
* SQL Table Implementation:
sql
CREATE TABLE Vehicle (
VehicleID INT PRIMARY KEY,
Make VARCHAR(50),
Model VARCHAR(50)
);
CREATE TABLE Car (
VehicleID INT PRIMARY KEY,
FOREIGN KEY (VehicleID) REFERENCES Vehicle(VehicleID),
EngineType VARCHAR(50)
);
CREATE TABLE Truck (
VehicleID INT PRIMARY KEY,
FOREIGN KEY (VehicleID) REFERENCES Vehicle(VehicleID),
CargoCapacity INT
);
* This structurepreserves the IsA relationshipbetween Vehicle (supertype) and Car/Truck (subtypes).
Why Other Options Are Incorrect:
* Option A (Strong entity) (Incorrect):Strong entitiesdo not rely on a supertype/subtype hierarchy.
* Option C (Associative entity) (Incorrect):Used toresolve many-to-many relationships, not supertype
/subtype relationships.
* Option D (Weak entity) (Incorrect):Weak entitiesdepend on a strong entity, but supertype-subtype relations useinheritance(not dependency).
Thus, the correct answer isIsA relationship, as it describes theinheritance hierarchybetweensupertypes and subtypes.
NEW QUESTION # 63
What is information independence?
Answer: A
Explanation:
Information independencerefers to theseparation between data storage and data access. It allows a database'slogical structureto be modifiedwithout affecting existing applications.
Types of Information Independence:
* Logical Data Independence# Ability to change theconceptual schema(e.g., renaming columns, adding new attributes)without modifying applications.
* Physical Data Independence# Ability to change thephysical storage structure(e.g., indexing, partitioning)without affecting queries.
Example of Logical Data Independence:
* Anew columnis added to the Customers table, but existing queriesstill work without modification.
Example of Physical Data Independence:
* Data is moved to SSD storagefor performance improvement, but queriesrun the same way.
Why Other Options Are Incorrect:
* Option A (Incorrect):Changing thedatabase type(e.g., MySQL to PostgreSQL) isnotinformation independence.
* Option B (Incorrect):Making changes toqueriesis unrelated to database independence.
* Option C (Incorrect):Interchanging databases is related todata portability, notinformation independence.
Thus, the correct answer isD - An ability to change the organization of data, asinformation independence ensuresmodifications do not disrupt database operations.
