Software Architecture: Design Goals and Typical Activities

Play an AI-generated podcast conversation about this lesson

What is the main purpose of identifying design goals in system design?

To define access control policies

To determine performance and cost requirements (correct)

To implement persistent storage

To ensure fault tolerance

How are components and connectors described in the context of software architecture?

Components are functional pieces of software, while connectors are the ways they communicate with each other at runtime. (correct)

Components and connectors both describe the properties of software elements.

Components and connectors are structures comprised of software elements.

Components are the ways software elements communicate with each other, while connectors are functional pieces of software.

What does allocation structure involve in software architecture?

Ensuring fault tolerance in software components

Mapping software modules to different aspects of the system’s environment (correct)

Identifying persistent storage requirements for the software

Defining access control policies for software elements
