1. Intro

  • How it differs from DB centric architecture?

2. Domain-centric architecture

  • E.g. of solar system

  • First people though earch at center

  • Shift in perspective.

  • Makes more elegant due to the shift of thinking

  • Similar in Software Architecture

  • Initial - database at center

  • Now - domain

  • Domain is central and database outside

  • First concern of architect, to make house usable

  • Essential vs Detail, House

  • Space is essential

  • usability is essential
  • Building materal is just detail

  • Oranmentation is detail

  • Clean Architecture

  • Domain is essential

  • Use cases are essential
  • presentation is a detail

  • persistence is a detail

  • What is central vs what is detail

  • Also incorporates BCE

  • All put domain model in the center

Pros:

  1. Focus on domain
  2. Less coupling between domain logic and implementation logic
  3. Allows for domain-driven-design

Cons:

  • Change is difficult (people may have no idea about this)
  • Requires more though
  • Higher initial cost
