Notes from "Clean Architecture" - Robert C. Martin

Part I: Introduction

What is design and architecture

"Architecture" is often used in the context of something at a high level, whereas "design" more often seems to imply structures and decisions at lower level. But this usage is nonsensical. In software design the low-level details and the high-level stucture are all part of the same whole, there is a continuum of decisions from the highest to the lowest levels.
