4. Domain Modeling & Boundaries
4. Domain Modeling & Boundaries
Model business domains, bounded contexts, aggregates, and dependency boundaries.
Lesson overview
4. Domain Modeling & Boundaries
Model business domains, bounded contexts, aggregates, and dependency boundaries.
This chapter develops the concepts progressively and connects them to real production engineering decisions. Focus on reasoning, trade-offs, failure modes, and measurable outcomes.

Step 1
Theory
Learning goals
Model business domains, bounded contexts, aggregates, and dependency boundaries.
You should be able to explain the concepts, compare alternatives, and apply them to a real production system.
Step 2
Example
Example
Apply 4. Domain Modeling & Boundaries to a realistic production scenario and trace the decision step by step.
Step 3
Code
Code
Add implementation notes or a runnable example for this concept.
Step 4
Practice
Review the chapter and write an architecture note explaining how its concepts apply to a system you know.
Step 5
Quiz
Quiz coming soon.
Step 6
Challenge
Design a small production system using this chapter and document at least three trade-offs.
