Sunline proudly announces the successful go-live of the Shanghai Bank New Generation Core System on October 7th, following 27 months of intensive development and partnership. This achievement is not merely a system upgrade; it is a critical strategic movement by Shanghai Bank to implement ONE BOS (Business Operating System) philosophy, drive deep digital transformation, and redefine core competitiveness for the future.
The new system’s mandate was clear: to establish a stable core engine for future growth, prioritizing security and independent control, customer-centricity, integrated domestic and foreign currency capabilities, agile business development support, and omnichannel integration.
Architectural Innovation: Rebuilding the Financial Service Engine
The transformation followed a “Business + Technology” deep integration path, achieving simultaneous upgrades to both architectures for a profound leap in management and service capabilities.
On the business side, it constructs a four-in-one core architecture of “Client – Product – Contract – Account” realizing componentized configuration and channel convergence, effectively supporting the system’s stable operation and agile business development. On the technical side, relying on the self-developed “Beidou” distributed foundation, it adopts a “Cell deployment + microservices” design pattern, achieving efficient service decomposition and rapid, elastic capacity expansion. This calmly handles high-concurrency scenarios and reserves ample space for subsequent business innovation and functional iteration.
Process Reshaping: Forging an Efficient, Collaborative “Implementation Paradigm”
Through a componentized modeling methodology, the new system breaks down strategic capabilities and functional requirements into reusable, standardized components, such as Account, Contract, Pricing, and Limit. This achieves the flexible assembly and rapid deployment of business functions, ensuring a timely response to market changes and dynamic customer needs.
Concurrently, a full life-cycle closed-loop management system has been established around the seven key phases: Requirement, Analysis, Design, Development, Testing, Deployment, and Cutover. This system facilitates the deep integration of business requirements and technical implementation, utilizes standardized processes to mitigate implementation risks and ensure smooth transitions between all stages, and relies on “factory-style” efficient collaboration to enhance project promotion effectiveness, providing high-efficiency support for high-quality business development.
Technical Autonomy: Fortifying the “Digital Foundation” for Intelligent Transformation
With the solid backing of a modernized cloud infrastructure, Shanghai bank has embraced cloud-native technology to construct a comprehensive “Beidou” (Navigation/Digital Compass) Technical Ecosystem. This ecosystem is a powerhouse, deeply integrating critical capabilities:
• Standardized Routing
• Microservice Governance
• One-Click Deployment for Large-Scale Distributed Systems
• Multi-Active Disaster Recovery Switchover
• Intelligent Observability
Through a platformized and componentized construction path, this system ensures the rapid output and highly efficient supply of foundational technical capabilities.
Shaping the Full-Link “Customer Journey”
Adhering to the core philosophy of “Customer-Centricity” the new system uses the “Customer Journey” as its guiding thread, driving process re-engineering and channel synergy to build a full-link, intelligent, and context-aware service ecosystem. Key improvements highlight efficiency and seamlessness:
• Streamlined Authentication: By integrating steps like queueing, identity verification, processing, and evaluation, the system achieves highly efficient coordination—for example, requiring “one-time verification, one-time card swipe.”
• Optimized High-Frequency Services: Exclusive, streamlined processes have been created for high-demand tasks such as comprehensive balance inquiries, boosting processing efficiency and overall service experience.
Product Empowerment: Supporting Digital Operations with “Precision Alignment”
Central to the upgrade is enabling digital customer management. The new system enriches diverse product scenarios and significantly strengthens functional adaptability. On one hand, it optimizes core business functions to focus on personalized customer needs, supporting services such as:
• Customized JiXiang Accounts (吉祥账户 – accounts with self-selected features).
• Multiple Withdrawals for Large-denomination Certificate of Deposit
• Card Replacement without changing the card number
This better meets varied and differentiated customer demands. On the other hand, it reinforces digital pricing support capabilities, allowing for differentiated pricing on deposit interest rates and intermediary service fees based on multiple dimensions, including: customer segment, channel, region, institution, and client size. This ensures a rapid response to dynamic market changes.
Simultaneously, a five-layer digital account system has been built, encompassing models like “All in One Account,” “One Account, Multiple Media,” and “Group Master/Sub-Accounts.” This flexibility precisely adapts to various business scenario requirements, comprehensively solidifying the functional support for digital customer management and accurately addressing diverse and personalized customer needs.
Risk Control Upgrade: Building a “Dual Defense Line” for Safety and Efficiency
The new system constructs a scenario-based, multi-layered account and fund risk control framework, covering core scenarios such as transfer, spending, and investment. This achieves multi-dimensional control across customer, medium (e.g., card/device), and account, supporting the flexible, configuration-based adaptation of risk control strategies. By balancing risk prevention with business efficiency, it ensures fund safety while simultaneously enhancing service convenience.
System Performance & Industry Leadership
Since its formal launch, the bank’s new core system has demonstrated stability and significant results:
• Daily Average Transaction Volume: 24 million
• System Peak Load Capacity: Increased by over 7 times
• Online Single Transaction Average Time: Decreased by 37.2%
• End-of-Day Batch Processing Time: Shortened by 77.8%
• Transaction Success Rate: Reached 99.999%
The successful construction and deployment of this new-generation core system is the culmination of three decades of the bank’s deep commitment to fintech and its “Customer First” service philosophy. It marks a qualitative leap in the bank’s technological hard power, positioning it among the leading City Commercial Banks and establishing it as a benchmark for technological empowerment among regional banks.
Looking Ahead: A Foundation for the Future
As 2025 marks Shanghai bank’s 30th anniversary, the successful launch of the new core system is both a significant gift celebrating the milestone and a solid technological foundation for the institution’s “15th Five-Year Plan” development blueprint. The bank will seize this opportunity to continue deepening the integration of technology and business, accelerating the pace of innovation, and creating sustained value for its customers, shareholders, and society through more stable, intelligent, and efficient financial services, stepping together toward a new journey.
