Payment domain modeling

Payment domain modeling is the second step in the theoretical framework for building an Aggregate payment system from scratch.^[600-developer__principle__aggregate-payment-system.md] It follows the initial analysis of the system's core value and serves as a prerequisite for applying a Microservices architecture.^[600-developer__principle__aggregate-payment-system.md]

Context in System Design

The creation of a payment domain model is part of a sequence of architectural decisions. While the first step focuses on understanding the business value ("浅谈聚合支付的核心价值"), the modeling step translates these business needs into a structured domain representation.^[600-developer__principle__aggregate-payment-system.md] This representation is essential before the system can be broken down into microservices ("应用微服务架构").^[600-developer__principle__aggregate-payment-system.md]
