Questions and Answers

1.

There is 4 degrees of relationships.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
B. FALSE

Explanation
The statement "There is 4 degrees of relationships" is incorrect. The correct statement should be "There are 3 degrees of relationships." In social network analysis, the concept of degrees of relationships refers to the number of connections or steps required to reach another individual within a network. The three degrees of relationships are: 1) First-degree connections (direct connections), 2) Second-degree connections (connections of connections), and 3) Third-degree connections (connections of connections of connections).

Cardinality constraints are the number of an entity in one instance that can or must be associated with each instance of another entity.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
B. FALSE

Explanation
Cardinality constraints are not about the number of an entity in one instance that can or must be associated with each instance of another entity. Instead, cardinality constraints define the relationship between entities in a database, specifying the number of occurrences of one entity that are associated with a single occurrence of another entity. Therefore, the given statement is false.

3.

The relationship is an association among the instances of one or more entity types that are not of interest to the organization.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
B. FALSE

Explanation
The statement is false because the relationship in a database represents an association among instances of one or more entity types that are of interest to the organization. Relationships are used to connect and establish connections between different entities in a database, allowing for the organization and retrieval of data based on these associations.

4.

Relationship instance is a meaningful association between (or among) entity type.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
B. FALSE

Explanation
The statement is false because a relationship instance is not a meaningful association between entity types. Instead, a relationship instance represents a specific occurrence or connection between individual entities in an entity type. It is the actual occurrence of the relationship, rather than a general association between entity types.

5.

A ternary relationship is a simultaneous relationship between the instance of 2-3 entity types.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
B. FALSE

Explanation
A ternary relationship is a simultaneous relationship between the instances of three entity types, not just two or three. Therefore, the given statement is false.

Rate this question:
6.

Entity is a verb and relationship is a noun.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
B. FALSE

Explanation
The explanation for the given answer is that the statement is incorrect. The term "entity" refers to a general object or thing, which can be a noun or a verb. Similarly, the term "relationship" can also be used as both a noun and a verb. Therefore, the statement that entity is a verb and relationship is a noun is false.

7.

Degree is the number of entity types that participate in a relationship.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
A. TRUE

Explanation
The statement is true because degree refers to the number of entity types that participate in a relationship. In other words, it represents the number of entities involved in a relationship. The degree can be unary, binary, ternary, etc., depending on the number of entity types involved. For example, a binary relationship involves two entity types, while a ternary relationship involves three. Therefore, the given statement is correct.

8.

Minimum Cardinality is the minimum number of instances of one entity that may be associated with each instance of another entity.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
A. TRUE

Explanation
The explanation for the given correct answer is that minimum cardinality refers to the minimum number of instances of one entity that can be associated with each instance of another entity. In other words, it determines the minimum number of relationships that must exist between two entities. Therefore, the statement that minimum cardinality is the minimum number of instances of one entity that may be associated with each instance of another entity is true.

Maximum cardinality is the maximum number of instances of one entity that may be associated with each instance of another entity.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
A. TRUE

Explanation
The statement is true because maximum cardinality refers to the maximum number of instances of one entity that can be associated with each instance of another entity. It determines the upper limit of the relationship between two entities, indicating how many instances of one entity can be linked to each instance of the other entity.

Rate this question:
10.

The unary relationship is the relationship on itself.
- A.
  
  TRUE
- B.
  
  FALSE
Correct Answer
A. TRUE

Explanation
In a unary relationship, a single entity is related to itself. This means that an entity within a certain domain is associated with another entity within the same domain. This relationship is often used to represent hierarchical or recursive structures, where an entity can have a relationship with other entities of the same type. Therefore, the statement "The unary relationship is the relationship on itself" is true, as it accurately describes the nature of a unary relationship.
