Question 1

This document system is used by systems professionals to show the logical design of a system.The advantage of the method is that it uses only four symbols.Identify the document system.

Accepted Answer

A Data Flow Diagram (DFD) is a graphical representation of the flow of data through an information system. It uses only four symbols to show the logical design of the system, which are: circles to represent processes, arrows to represent data flow, open-ended rectangles to represent sources and sinks of data, and closed-ended rectangles to represent data stores. DFDs are used by systems professionals to analyze, design, and document information systems.

Question 2

A Data Flow Diagram is used by systems professionals to show the logical design of a system.The advantage of the method is that it uses only four symbols.The symbol used to represent both sources and destinations of data is a(n):

Accepted Answer

A square with squared corners is used to represent both sources and destinations of data in a Data Flow Diagram.

Question 3

When creating or reading a system flowchart, the triangle symbol represents a:

Accepted Answer

The triangle symbol in a system flowchart represents a file, indicating storage of data or information.

Question 4

When discussing entity relationship diagrams, this is considered to be a characteristic of an entity.

Accepted Answer

An attribute is a characteristic or property of an entity in an entity relationship diagram. It describes the specific information or data that an entity represents. Examples of attributes might include a person's name, age, address, or gender. Attributes are represented as ovals in an ERD.

Question 5

The rectangle used in an entity relationship diagram is used to represent a(n):

Accepted Answer

The rectangle in an entity relationship diagram is used to represent an entity, which is a real-world object or concept that has a unique identity and is distinguishable from other objects or concepts. Attributes and relationships are also included in an entity relationship diagram, but they are represented using different symbols.

Question 6

The oval used in an entity relationship diagram is used to represent a(n):

Accepted Answer

In an entity-relationship diagram (ERD), an oval is used to represent an attribute, which is a property or characteristic of an entity.

Question 7

The diamond used in an entity relationship diagram is used to represent a(n):

Accepted Answer

The diamond in an entity relationship diagram represents a relationship between two entities. The attributes of the entities are represented by ovals and the entities themselves are represented by rectangles.

Question 8

When creating or reading a system flowchart, the diamond represents a(n):

Accepted Answer

The diamond shape in a system flowchart represents a decision point where multiple paths can be taken based on a condition or criteria. Therefore, option B, "Decision" is the correct answer. A refers to an on-page connector, which is a symbol used to connect different sections of the same page when there is not enough space, C refers to data, and D refers to a process.

Question 9

This document system is a pictorial representation of the logical structure of databases.It identifies the entities, the attributes of the entities, and the relationship between the entities.

Accepted Answer

An Entity Relationship Diagram (ERD) is specifically designed to identify entities, attributes, and relationships between them, which matches the description provided in the question. The other choices, such as System Flowchart, Entity Flowchart, or Process Map, do not necessarily focus on databases or the relationships between entities within a database system.

Question 10

A Data Flow Diagram is used by systems professionals to show the logical design of a system.The advantage of the method is that it uses only four symbols.The symbol used to represent a data store or the storage of data is a(n):

Accepted Answer

An open-ended rectangle is the symbol used in Data Flow Diagrams (DFDs) to represent a data store or the storage of data. This symbol visually differentiates where data is stored within the system being diagrammed.

Question 11

When discussing entity relationship diagrams, this is considered to be a noun, that represents items in the accounting system:

Accepted Answer

Entities are the items or "things" in an accounting system that are represented in the entity relationship diagram. These could include things like customers, products, bank accounts, and invoices. Attributes describe characteristics of these entities, while relationships represent how they interact with each other. Flows are not typically used in entity relationship diagrams.

Question 12

When creating or reading a system flowchart, the rectangle represents a(n):

Accepted Answer

In a system flowchart, the rectangle is used to represent a process. It signifies an action or activity being performed within the system.

Question 13

Which of the following statements, regarding ethical considerations in an accounting information system is false?

Accepted Answer

If there is only one person responsible for maintaining the computer systems, it could be easier for that person to commit computer fraud without being detected. This statement is false as it suggests the opposite.

Question 14

A Data Flow Diagram is used by systems professionals to show the logical design of a system.The advantage of the method is that it uses only four symbols.The symbol used to represent any task or function performed is a(n):

Accepted Answer

The symbol used to represent any task or function performed in a Data Flow Diagram (DFD) is a rectangle with rounded corners, which is known as a process symbol.

Question 15

The term that refers to how many instances of an entity relates to each instance of another entity is:

Accepted Answer

The term that refers to how many instances of an entity relates to each instance of another entity is called cardinality. Cardinality specifies the possible number of occurrences in one entity which are associated with the number of occurrences in another entity.

Question 16

A Data Flow Diagram is used by systems professionals to show the logical design of a system.The advantage of the method is that it uses only four symbols.The symbol used to represent the flow of data is a(n):

Accepted Answer

The arrow symbol is used to represent the flow of data in a Data Flow Diagram. The rectangle with rounded corners represents a process, the open-ended rectangle represents an external entity, and the rectangle with squared corners represents a data store.

Question 17

The documenting system that shows the flow of documents and information among departments or units within an organization is called a:

Accepted Answer

A Document Flowchart shows the flow of documents and information among departments or units within an organization, making it the best choice for this scenario. System Flowcharts show the flow of data or information within a computer system, ER Diagrams show the relationships between entities in a database, and Data Flow Diagrams show the flow of data through a system.
