Lecture 1-Intro

Question 1

What are the dimensions of software architecture ?

Answer 1

1.Structure
2.Architecture characterisitics
3.Architecture decisions
4.Design principles

Question 2

How do we define the structure dimension ?

Answer 2

Type of architecture style (or styles) the system is implemented in.

Ex: microservices, layered or microkernel

Question 3

How do we define the architecture characteristics dimension ?

Answer 3

It defines the success criteria of a system, which is orthogonal to the functionality of the system.
*DONT REQUIRE KNOWLEDGE OF THE FUNCTIONALITY, BUT ARE REQUIRED TO FUNCTION

Question 4

How do we define the architecture decisions dimension ?

Answer 4

They define the rules for how a system should be constructed.

Question 5

Which describes a software architect’s role?

Answer 5

Overseeing the high-level design and structure of a software system.

Question 6

What does the term “software architect” encompass?

Answer 6

Both the high-level structure and the low-level details of a software system.

Question 7

What is software design?

Answer 7

The process of defining the architecture, components, interfaces, and other characteristics of a system or component and the result of that process.

Question 8

What are the two types of software design?

Answer 8

1.Software architectural design(high-level design)
2.Software detailed design

Question 9

How does software architectural design consist of ? (called high-level design)

Answer 9

It develops top-level structure and organization of the software and identifies the various components.

Question 10

How does software detailed design consist of ?

Answer 10

It specifies each component in sufficient detail to facilitate its construction.

Question 11

Explain requirements vs design.

Answer 11

Requirements:
-Problem
-What stakeholders wants
*BUILDING THE RIGHT SYSTEM

Design:
-Engineering solution to the problem.
-HOW????
*BUILDING THE SYSTEM RIGHT

Question 12

Explain OOP analysis vs design.

Answer 12

Analysis: finding and describing objects and concepts.
Design: defining software objects and how they meet requirements.

Question 13

What are the 4 steps to go from OOP analysis to design?

Answer 13

1. Define user cases
   2.Define a domain model
   3.Assign object responsibilities + draw interaction diagrams
   4.Define design class diagrams
