How GBase Database Supports Banks' Mission-Critical Business from Edge to Core

Published on 2025-10-27

As the wave of IT application innovation sweeps through the financial industry, how can banks rely on locally-developed databases to anchor the stability of their core business? A city commercial bank in South China has answered this with concrete data: its management cockpit has run stably for over 1,000 days, peak fund query throughput hits 20,000 queries per second, and a full-stack domestic architecture delivers 24/7 uninterrupted service. Behind all this is the robust support of the GBase database.

The Road to Digital Transformation for a Regional City Commercial Bank

Founded in the 1990s in South China, this bank evolved from an urban credit cooperative to a top-50 player in China's banking industry—a genuine force influencing the pulse of regional finance. More notable, however, is its pioneering role in the realm of IT application innovation.

As early as 2022, faced with explosive credit card business growth and an urgent need for faster decision-making, the bank decisively chose to “change lanes and overtake”—replacing foreign products with a locally-developed database and equipping its core business systems with a “Chinese heart.” Its chosen partner was GBase 8s, a database with two decades of deep domain expertise. This collaboration was not just about meeting the financial sector’s extreme demands for high availability, high stability, and high compatibility; it also aimed to deliver a replicable blueprint for domestic IT innovation.

Steady Progress from Pilot to Scale

The partnership between GBASE (General Data Technology Co., Ltd.) and the city commercial bank in South China began with a technical exchange in early 2022. When GBASE presented GBase 8s performance reports and financial sector case studies to the bank, neither side could have predicted that this routine technical engagement would blossom into a deep collaboration spanning three years.

  • September 2022: The Credit Card Center’s management cockpit went live. This system aggregates multi-dimensional indicators—business development, risk compliance, inclusive finance—into a “decision-making brain,” enabling management to monitor operational dynamics through visual dashboards in real time, all supported by GBase 8s.

  • November 2024: Two more systems went into production. The unified identity authentication system enables “one login across the entire bank,” freeing employees and customers from repeated verifications. The Morning Star application system acts as a “fund data hub,” pulling in third-party data through dedicated lines and delivering tens of thousands of queries per second to channels such as mobile banking and smart teller machines.

  • April 2025: The green finance management system made its grand entrance. As a key tool to support the bank’s goal of reaching 100 billion RMB in green financing by 2025, it leverages GBase 8s to store environmental benefit calculations, carbon emission accounting, and related data, significantly boosting the approval efficiency of green loans.

From a single-system pilot to multi-scenario, scaled deployment, GBase 8s has firmly established itself in the core business landscape of this city commercial bank over three short years.

Four Key Advantages of GBase 8s

In the financial world, requirements for a database are unbelievably stringent: it must withstand tens of thousands of queries per second, achieve sub-second failover with zero data loss, and remain compatible with existing Oracle code and tooling. How does GBase 8s deliver on all fronts?

  • High Availability: Like a Double Safety Net

Utilizing comprehensive high-availability solutions such as SSC, HAC, and RHAC, GBase 8s enables sub-second automatic failover when the primary node fails, while the secondary node remains unaffected. It easily meets financial-grade standards of RPO=0 (zero data loss) and RTO<30 seconds. Even under extreme conditions, the system remains steady, much like a roly-poly toy.

  • Compatibility: Seamless Integration with Legacy Systems

With 92% data type compatibility and 96% coverage of basic functionalities, GBase 8s can directly leverage Oracle’s PL/SQL syntax, triggers, and stored procedures. Paired with the MTK visual migration tool, what would normally take months to migrate from Oracle was completed by the bank’s team in just a few weeks, tackling even tough challenges such as trigger rewriting with ease.

  • Performance: Stable and Lightning Fast

The advanced DSA (Dynamic Scalable Architecture) fully utilizes server resources; in a 500-warehouse benchmark, TPCC testing achieved 1.6 million TPMC. During peak periods on the Morning Star system, 20,000 fund queries per second are handled effortlessly, with response latency consistently in the millisecond range.

  • Full-Stack Adaptation: A Complete Domestic Ecosystem

From Huawei Kunpeng chips and Kylin operating systems to TongTech middleware, GBase 8s acts as a “universal interface,” seamlessly integrating into China’s domestic software and hardware stack. This end-to-end compatibility capability has helped the bank avoid countless detours on its IT innovation journey.

Behind 1,000 Days of Stability: IT Innovation Adds Value

Today, the operations dashboard of this city commercial bank in South China tells a compelling story:

  • The management cockpit has run continuously for 1,000 days, supporting numerous critical management decisions;

  • High-performance capabilities meet daily business demands, with the Morning Star system handling peak loads of 20,000 queries per second without a single error;

  • The full-stack domestic architecture has reduced IT operational costs by more than 25%.

For the bank, this innovation practice has long transcended simple “replacement”: it proves that locally-developed databases can not only “take over” core financial operations, but also serve as an “accelerator for business innovation.” The green finance system, for instance, relies on GBase 8s’s efficient data processing to rapidly calculate corporate carbon emissions, enabling green loans to be deployed with precision.

For the broader industry, this case provides a valuable reference—when a bank can run a locally-developed database stably for three years and effortlessly handle 20,000 queries per second, the viability of domestic IT innovation no longer needs any further proof.

From this financial IT innovation practice, we see not merely the triumph of a database product, but the leap of domestic technology from “functional” to “premium.” As more financial institutions join the innovation movement, the GBase database will undoubtedly continue to surprise—after all, delivering a perfect score under the intense pressure of the financial “exam room” is never just a matter of luck.
