With the increasing volume of data, the complexity of business logic, and the rise of microservices architecture, the traditional CRUD model—Create, Read, Update, Delete—and ORM patterns face challenges in scalability and data consistency. Consequently, Event Sourcing (ES) has been proposed as a potential solution. Unlike traditional methods that only store the final state, ES records all changes leading to that result. This not only provides a complete history and audit trail of system state changes but also enhances system scalability in handling large-scale data operations and ensures data consistency in distributed systems. Although the traceability and auditability of ES are theoretically acknowledged, there is still limited research on the performance impact of systems adopting ES at the implementation level. This study explores the application of the ES architecture in modern software systems, particularly its impact on system performance and scalability. To this end, the research uses the JPetStore e-commerce website as a case study, implementing different architectural designs, including the traditional CRUD-based architecture and its variants integrating ES. Through these implementations, this study aims to provide empirical evidence to support discussions on system design and technical considerations. Additionally, the study addresses challenges in implementing ES, such as technical complexity and event design. Implementing ES requires developers to have a deep understanding of business processes and to manage various state changes triggered by events. This thesis, through in-depth analysis and comparison of different architectures, reveals the specific impacts of adopting ES on software system performance and shares insights from the process of refactoring from traditional CRUD to ES architecture.參考文獻 [1] J.
