Accepted Answer

The answer of One technique to find the "things" that...

Question 2

A synonym for cardinality (used with UML class diagrams)is ____.​

Accepted Answer

In UML class diagrams, cardinality refers to the number of instances of one class that can be associated with the instances of another class. This concept is represented by multiplicity, which is a synonym for cardinality in this context. Choice A) relationship is too general to be a synonym for cardinality specifically in UML class diagrams. Choice C) unary relationship refers to a relationship between instances of a single class, which is not the same as cardinality. Choice D) inheritance is a different concept in object-oriented programming that refers to the ability of a subclass to inherit properties and methods from a superclass.

Question 3

When making a list of nouns to determine what are the important "things" for the new system,there are three question that should be asked about each noun. Which of the following is one of those questions?​

Accepted Answer

The answer of When making a list of nouns to...

Question 4

The below cardinality constraint on the Order data entity indicates that there can be _____ .

Accepted Answer

The cardinality constraint "one or many" indicates that there must be at least one order, but there can be multiple orders associated with the entity.

Question 5

A relationship between a "sports team" and the players,coaches,and sponsor would be described as what kind of relationship?​

Accepted Answer

Aggregation is the correct answer because it represents a whole/part relationship where the parts (players, coaches, and sponsor) can exist independently of the whole (sports team).

Question 6

A piece of information about a particular object is called a(n)_______.​

Accepted Answer

An attribute is a piece of information about a particular object. It is a characteristic or property of the object that helps to describe or identify it. Examples of attributes could be color, size, weight, or shape.

Question 7

A measure of the number of links between one object and another object in a relationship is called the _______.​

Accepted Answer

The measure described in the question is known as cardinality, which refers to the number of links between two objects in a relationship. The other options (A, B, and C) are related to object-oriented programming and software design, but do not accurately describe the concept of cardinality.

Question 8

____ is used to describe the relationship between two things of the same type,such as one person being married to another person.​

Accepted Answer

Unary association is used to describe a relationship where an entity is related to itself, such as one person being married to another person, both of whom are of the same type (people).

Question 9

An attribute that contains a collection of related attributes is called a(n)_______.​

Accepted Answer

A compound attribute contains a collection of related attributes. The other options are not relevant to this definition.

Question 10

An attribute whose value uniquely identifies an object is called a(n)_______.​

Accepted Answer

A key attribute uniquely identifies an object within a database. It is used to ensure that every object has a distinct identity and can be accessed and manipulated uniquely without confusion.

Question 11

The crows feet notation on an ERD is a type of _______ constraint.​

Accepted Answer

The crows feet notation on an ERD represents the cardinality constraint, which shows the number of entities that can be involved in a relationship. It depicts whether a relationship is one-to-one, one-to-many, or many-to-many.

Question 12

One technique for finding "things" that need to be in the new system is done by the analyst starts making lists of "things."  He may do this from information and even without talking to the users extensively. This technique is called the _______.​

Accepted Answer

The noun technique involves the analyst making lists of "things" (nouns) that are relevant to the system, often derived from documentation or descriptions of the current system, without necessarily requiring extensive discussions with users. This helps in identifying entities or objects that need to be considered in the new system.

Question 13

The domain model class diagram is used to _______ .​

Accepted Answer

The domain model class diagram is used to represent the things involved in the user's work that are important, focusing on the conceptual perspective rather than software or data entities.

Question 14

In the traditional approach to system development,the system stores information about ____.​

Accepted Answer

In the traditional approach to system development, the system stores information about data entities. Data entities are the objects or concepts about which data is stored. They represent a discrete piece of information that is relevant to the system, such as a customer, product, or order. Attributes refer to the characteristics or properties of a data entity and data stores refer to the physical location where data is stored.

Question 15

A synonym for cardinality (used with UML class diagrams)is _______.​

Accepted Answer

The term "multiplicity" is commonly used in UML class diagrams to refer to the cardinality of a relationship between classes. It indicates how many instances of one class can be associated with one instance of the other class.

Question 16

A(n)_______ is a naturally occurring association among specific things.​

Accepted Answer

A relationship is the best choice as it refers to the connection or association between specific things. The other options do not accurately refer to a naturally occurring association between specific things.

Question 17

An example of an attribute of an object might be _______.​

Accepted Answer

A social security number is a specific attribute that identifies an individual. The other choices describe objects or collections of objects, but do not specify a particular attribute.

Question 18

The association shown on the below image is a(n)________  association.

Accepted Answer

The answer of The association shown on the below image...

Question 19

The number of associations that occur among specific things in an entity relationship diagram is called ____.

Accepted Answer

The number of associations between specific things in an entity relationship diagram is referred to as cardinality. Cardinality is a significant aspect of determining relationships between entities, as it helps to explain the join between entities in terms of the occurrence of the related object. Thus, among the options given, D is the correct answer.

Question 20

A relationship that has a cardinality constraint of one or more is a(n)  _______ relationship.​

Accepted Answer

A cardinality constraint of one or more means that the relationship is mandatory, as there must be at least one instance of the related entity for each instance of the primary entity. "Optional" (B) would refer to a relationship where there may or may not be a related entity for each instance of the primary entity. "Unary" (C) would refer to a relationship where there is only one entity involved (such as a person and their birthdate). "Binary" (D) refers to a relationship between two entities.
