What is software architecture?• Software architecture refers to

the high-level structures of a software system.

• Structures are interleaved with each other

• Without a good software architecture, it will be impossible to implement all of the desired quality attributes.

Motivation

• Different software architectures have their own characteristics, and usually developers have little idea about how to use a software architecture in a proper way.

• My project aims to explore how to apply the concepts of design patterns and clean architecture in real-world software and how to help developers to recognize how to make their software architectures better.

Introduction to “Clean Architecture”

5

From an abstract level to general level from the inside to the outside• Entities include enterprise business

rules and depends on domain models. • Use cases are application business

rules; they depend on the inner layer of entities

• External interfaces: The most appropriate framework for the whole software

• Adapter layer: 1. Implements interfaces which are

supported by use cases 2. Control data flow 3. Interacting with applications

Why “Clean Architecture” ?

• Independent of frameworks• Testable• Independent of database• Independent of UI• Independent of any external agency

6

Introduction to Django Framework• Django is a high-level web framework written in the

Python programming language which is effective and efficient on the development and maintenance of websites.

• Used in Techlauncher projects!• Advantages:

– Fast– Fully loaded– Secure– Scalable– Versatile

Two case studies

• FutureYou

• ANU Fifty50

Analysis Metholdology

• Concepts from “Clean Architecture” by Robert C Martin, a.k.a. Uncle Bob

• Properties analysed following ideas from the dissertation: “Architectural styles and the design of network-based software architectures ” byRoy Fielding

• Hypothetical scenarios evaluated to analyse properties such as “extensibility”

9

FutureYou

• An online gamifying career planning and development platform, supported by ANU Student Experience & Career Development (SECD).

• A web-application

• Career development & Engage in career life early.

ANU Fifty50

13

• ANU Fifty50 is a student-run online mentoring platform

• Aims to help mentees (junior students) to search, find, and pair with their mentors (senior students) automatically.

• Mentees can have tutorials with their mentorsand coaching content will be released every two weeks.
