Three Levels of Domain Modeling
- Domain modeling can be understood in three levels: data modeling, operation modeling, and algebraic modeling. - Each level represents a different abstraction and complexity in modeling domains.
Start With Data Modeling
- Start domain modeling with data modeling, as it is the most concrete aspect. - Mastering data modeling involves composing state using product types and sum types effectively.
Pizza Order Models Illustrate Concepts
- Pizza ordering exemplifies composition: size and sauce are product types, size is a sum type, and toppings are combinations with constraints. - Collections complicate state modeling but capture real-world choices elegantly.
