Data Flow Diagrams vs Flowcharts Quiz and Flashcards

One difference between system flowcharts and data flow diagrams is that system flowcharts show conditional logic whereas DFDs don't.

Multiplicity is a factor which is not associated with an attribute.

A derived attribute is computed from other attributes.

What is the purpose of a use case diagram in software development?

What distinguishes a Level One DFD from a Level Zero DFD?

A behaviorally related sequence of steps, both automated and manual, for the purpose of completing a single business task

What is Level Zero DFD?

Which of the following UML diagrams has a static view?

What should every data flow connect to in a Level One DFD?

System Flowcharts vs. Data Flow Diagrams

System flowcharts illustrate conditional logic, while data flow diagrams (DFDs) do not.

Multiplicity in Data Modeling

Multiplicity is a factor that defines the relationship between entities, not individual attributes.

Derived Attributes

A derived attribute is calculated from other attributes within a data model.

Use Case Diagram Purpose

A use case diagram in software development visualizes the interactions between users (actors) and the system, outlining the functionalities of the system.

Level One vs. Level Zero DFD

Level Zero DFD presents a high-level overview of the entire system, depicting its major processes and data flows.
Level One DFD provides a more detailed view of a specific process from the Level Zero DFD, breaking it down into subprocesses and their associated data flows.

Business Process Definition

A business process is a series of steps, both automated and manual, designed to complete a specific business task.

Level Zero DFD Definition

A Level Zero DFD represents the highest-level view of a system, showcasing its major processes and how data flows between them.

Static View UML Diagrams

Class diagrams offer a static view in Unified Modeling Language (UML), representing the structure and relationships between classes in a system.

Data Flow Connections in Level One DFD

In a Level One DFD, each data flow must connect to a process, either as input or output.
