【Abstract】 Purpose/Significance To achieve cross-province interoperability of electronic vaccination certificates, so as to enhance the continuity and management efficiency of public health services. Method/Process By analyzing cross-province interoperability business scenarios and data consistency requirements, an integrated technical solution is proposed, featuring the national platform as the coordination hub, event-driven as the core, three-tier hierarchical logical architecture as the support, and multi-level caching and conflict resolution as the guarantee. Result/Conclusion The solution achieves business closed-loop management based on the “one person, one file, one certificate” rule, ensuring business continuity and data consistency. It not only lays a solid technical foundation for the construction of electronic vaccination certificate systems across the country but also offers a reference solution for cross-regional collaboration in other government services.更多还原
