NEW QUESTION # 59
Which phase of entity-relationship modeling refers to the maxima and minima of relationships and attributes?

  • A. Attribute minimum
  • B. Physical design
  • C. Cardinality
  • D. Partition

Answer: C

Explanation:
Cardinalitydefines theminimum and maximum number of occurrencesof one entity in relation to another.
Example Usage in an ER Model:
* One-to-Many (1:M): Acustomer can place multiple orders, but each order belongs to onlyone customer.
Customers (1) --- (M) Orders
* Cardinality notation:
(1,1) # One-to-One
(0,M) # Zero-to-Many
(1,M) # One-to-Many
Why Other Options Are Incorrect:
* Option B (Physical design) (Incorrect):Focuses onstorage and indexing, not relationships.
* Option C (Attribute minimum) (Incorrect):No such formal term in database modeling.
* Option D (Partition) (Incorrect):Refers todividing tables, not relationship constraints.
Thus, the correct answer isCardinality, as it definesmin/max constraints on relationships.


NEW QUESTION # 60
Which type of entity only exists in a logical sense?

  • A. Concrete entity
  • B. Intangible entity
  • C. Tangible entity
  • D. Physical entity

Answer: B

Explanation:
Anintangible entityis an entity that does not have a physical presence but still holds meaning in a database.
These entities representconcepts, relationships, or abstract datathat exist in a logical sense.
Example Usage in Databases:
* Customer Loyalty Status (Gold, Silver, Bronze)
* Theloyalty levelis anintangible entitysince it is derived from other data (purchase history).
* Online User Sessions
* Asession IDexistslogically in the systembut does not have a tangible presence like a product or employee.
Why Other Options Are Incorrect:
* Option A (Concrete entity) (Incorrect):No such formal term in database design.
* Option B (Tangible entity) (Incorrect):Represents somethingphysical, like anemployeeorproduct.
* Option D (Physical entity) (Incorrect):Refers todata stored on disk, like database tables or indexes.
Thus, the correct answer isIntangible entity, as it only exists in a logical sense within the database.


NEW QUESTION # 61
How can a primary key constraint be added after the table is created?

  • A. By using an ALTER clause
  • B. By using the CREATE TABLE statement
  • C. By using an INSERT INTO clause
  • D. By using an UPDATE clause

Answer: A

Explanation:
Toadd a primary key constraint after table creation, we use theALTER TABLEstatement.
Example Usage:
sql
ALTER TABLE Employees
ADD CONSTRAINT PK_Employees PRIMARY KEY (EmpID);
* Thisaddsa primary key to the EmpID columnafter the table was created.
Why Other Options Are Incorrect:
* Option B (CREATE TABLE) (Incorrect):Used for defining constraintsduringtable creation, not after.
* Option C (UPDATE) (Incorrect):Modifiesrow values, not constraints.
* Option D (INSERT INTO) (Incorrect):Used toadd datato a table, not modify constraints.
Thus, the correct answer isALTER TABLE, as itmodifies table structure to add a primary key constraint.


NEW QUESTION # 62
Which keyword combines INSERTS, UPDATES, and DELETES operations into a single statement?

  • A. JOIN
  • B. INTO
  • C. DROP
  • D. MERGE

Answer: D

Explanation:
TheMERGEstatement, also known asUPSERT, combinesINSERT, UPDATE, and DELETEoperations into asingle statementbased on a given condition. It is commonly used indata warehouses and large-scale databases.
Example Usage:
sql
MERGE INTO Employees AS Target
USING NewEmployees AS Source
ON Target.ID = Source.ID
WHEN MATCHED THEN
UPDATE SET Target.Salary = Source.Salary
WHEN NOT MATCHED THEN
INSERT (ID, Name, Salary) VALUES (Source.ID, Source.Name, Source.Salary);
* If a match is found, the UPDATE clause modifies the existing record.
* If no match is found, the INSERT clause adds a new record.
Why Other Options Are Incorrect:
* Option A (INTO) (Incorrect):Used in INSERT INTO, butdoes not combine operations.
* Option B (JOIN) (Incorrect):Used to combine rows from multiple tables, butnot for merging data.
* Option D (DROP) (Incorrect):Deletes database objects liketables, views, and indexes, butdoes not merge data.
Thus, the correct answer isMERGE, as itcombines inserts, updates, and deletes into a single operation.


NEW QUESTION # 63
Which keyword is used to introduce a limiter in a SELECT statement?

  • A. INTO
  • B. DROP
  • C. WHERE
  • D. FROM

Example Usage:
sql
SELECT *
FROM Employees
WHERE Salary > 50000;
* This querylimitsthe result set to employees whose salary isgreater than 50,000.
Why Other Options Are Incorrect:
* Option A (FROM) (Incorrect):Specifies the table from which data is retrieved butdoes not limit results.
* Option B (DROP) (Incorrect):Used fordeleting tables, databases, or views, not filtering rows.
* Option C (INTO) (Incorrect):Used in statements like INSERT INTO or SELECT INTO, whichdo not filter results.
