- PHP development: Using EventSourcing and CQRS to achieve system architecture separation
- With the rapid development of the Internet, the development of large-scale systems has become an inevitable problem. The design and implementation of system architecture will directly affect the scalability, maintainability and reliability of the system. In traditional system development, a three-layer architecture (i.e., presentation layer, business logic layer, and data access layer) is usually used to achieve system layering and separation. However, as business requirements continue to develop and change, the traditional layered architecture model can no longer meet system requirements. EventSourcing and CQRS are currently more popular
