Deployment diagrams in Software Engineering - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a deployment diagram?

A deployment diagram is a type of diagram in software engineering that shows the physical arrangement of hardware and software in a system. It illustrates how software components are deployed on hardware nodes.

beginner

What are the main elements of a deployment diagram?

The main elements are nodes (hardware devices or execution environments), artifacts (software components or files), and communication paths (connections between nodes).

intermediate

How does a deployment diagram differ from a class diagram?

A deployment diagram shows the physical deployment of software on hardware, while a class diagram shows the logical structure of the software, like classes and their relationships.

Why are deployment diagrams important in software projects?

They help teams understand the hardware requirements, software distribution, and communication between components, which is essential for planning, testing, and maintenance.

beginner

What does a communication path represent in a deployment diagram?

A communication path represents the connection or network link between two nodes, showing how they communicate or exchange data.

What does a node represent in a deployment diagram?

A A database table

B A software class

C A user interface screen

D A hardware device or execution environment

Nodes represent physical devices or environments where software runs.

Which element shows software components in a deployment diagram?

A Node

B Artifact

C Communication path

D Package

Artifacts represent software components or files deployed on nodes.

What is the primary purpose of a deployment diagram?

A To show physical hardware and software arrangement

B To show software logic and classes

C To show user interactions

D To show database schema

Deployment diagrams focus on physical deployment of software on hardware.

In deployment diagrams, what does a communication path indicate?

A Connection between two nodes

B Data flow inside a software component

C Inheritance between classes

D User navigation flow

Communication paths show network or connection links between nodes.

Which of these is NOT typically shown in a deployment diagram?

A Hardware devices

B Software artifacts

C Class methods

D Communication paths

Class methods are part of class diagrams, not deployment diagrams.

Explain the purpose and main components of a deployment diagram.

Think about how software and hardware are shown together.

Describe how deployment diagrams help in software project planning.

Consider why knowing physical setup matters.
