Enterprise IT infrastructure is rapidly evolving around large-scale data processing, cloud-native architectures, and 24/7 service availability. As traffic and data volumes grow and security and disaster recovery (DR) requirements become more stringent, databases are expected to evolve beyond simple data storage into intelligent core engines that deliver greater performance, flexibility, and resilience.

Tibero7 is a next-generation DBMS designed to address the core challenges of enterprise and mission-critical environments. By fundamentally enhancing its core engine architecture, Tibero7 delivers more than 30% performance improvement over previous versions.

This article explores the key technologies enhanced in Tibero7 and the value they bring to enterprise data platforms

Key Change ①: Performance Innovation for Large-Scale Data

As AI services and digital transformation accelerate, enterprises are processing increasingly large volumes of data. Growing data volumes can slow query and analytics performance while increasing storage and infrastructure costs. Peak business hours can also create performance bottlenecks as large numbers of transactions occur concurrently.

Enterprises therefore need databases that can reliably handle growing data and transaction volumes.

Tibero7 addresses these challenges by enhancing its core data processing architecture. Improvements to memory management, parallel processing, and internal processing efficiency deliver more than 30% performance improvement compared with previous versions.

This is more than faster SQL execution. It represents an evolution of the underlying data processing architecture to maintain stable performance under high transaction loads.

Advanced Compression for Efficient Data Management

Tibero7 also enhances data compression capabilities to improve storage efficiency.

TCC (Tibero Columnar Compression) compresses data at the column level, providing high compression efficiency for large datasets with repetitive values. It can reduce storage requirements by up to 50–90%, while reducing disk I/O and contributing to improved query performance.

Tibero7 also provides:

• OLTP Compression to compress data in online transaction processing environments while minimizing performance impact
• Index Prefix Compression to reduce index size and improve memory utilization
• In-Memory Column Store (IMCS) to process frequently accessed data in columnar format directly in memory, improving performance for complex analytical queries and large-scale aggregations

Enhancements to the query optimizer further help deliver stable and consistent performance across diverse workloads.

Key Change ②: High Availability and Disaster Recovery for Continuous Operations

For enterprise systems, minimizing service disruption and data loss is critical. Unexpected failures or operational errors can directly affect business continuity, particularly in financial, public-sector, and manufacturing environments that operate 24/7.

Tibero7 significantly strengthens its high availability (HA) and disaster recovery capabilities, with the goal of minimizing RPO (Recovery Point Objective) and RTO (Recovery Time Objective) toward near-zero levels.

Automatic Block Repair (ABR) automatically retrieves a healthy block from a standby database when database block corruption occurs. This reduces recovery time without requiring administrator intervention.

Flashback Database enables the entire database to be restored to a specific point in time, helping organizations respond quickly to user errors and logical data issues.

Tibero7 also supports automatic resynchronization after recovery in Active-Standby environments, helping restore the replication configuration and improve operational stability.

In addition, Snapshot Standby, Cascade Standby, and Multi-Node Standby provide greater flexibility and scalability for DR architectures, including test environments and multi-standby configurations.

Key Change ③: Enhanced Operational Stability for Mission-Critical Environments

Unexpected performance degradation is one of the key concerns when upgrading a DBMS. Changes to SQL execution plans or statistics can affect application response times after an upgrade.

Tibero7 provides several capabilities to help identify and mitigate these risks before they affect production.

Database Replay reproduces production workloads in a test environment, allowing organizations to validate the performance impact of an upgrade in advance.

Pending Statistics enables new optimizer statistics to be evaluated before they are applied to production.

SQL Plan Management (SPM) helps retain validated SQL execution plans and prevent unexpected plan changes from causing performance degradation.

Together, these capabilities improve not only performance but also the stability and predictability of database operations.

Tibero7 Technology Proven in Real-World Environments

DBMS capabilities cannot be evaluated by feature lists alone. Real-world performance, operational stability, and the ability to handle large-scale and diverse workloads are equally important.

Tibero7 has demonstrated these capabilities through deployments across various enterprise environments.

Seoul National University of Science and Technology: Stable Performance Under High Traffic

Seoul National University of Science and Technology upgraded its database environment from Tibero5 to Tibero7 and saw significant improvements in system performance and operations.

During course registration periods, CPU utilization had previously remained at 100% for more than an hour. After the upgrade, the overload was resolved in approximately 10 minutes.

The university also uses T-Perf to reproduce production-like workloads and validate the impact of patches in advance, improving operational stability.

It is also considering TCC (Tibero Columnar Compression) to efficiently manage large volumes of log data that must be retained over the long term.

The case demonstrates how Tibero7 can improve not only performance but also operational efficiency and data management.

POSCO: Improving Global ERP Performance

POSCO upgraded ERP systems operating across six global regions from Tibero6 to cloud-based Tibero7.

Following the upgrade, month-end closing performance and user-perceived response times improved by more than 50%, improving the efficiency of its global ERP operations.

The system continues to provide stable services across environments used simultaneously by large overseas subsidiaries, demonstrating Tibero7’s ability to support core enterprise workloads.

Korea Workers’ Compensation & Welfare Service: 95% Faster Response Times

Korea Workers’ Compensation & Welfare Service migrated its Employment and Industrial Accident Insurance Total Service to a cloud-based MSA (Microservices Architecture) environment powered by Tibero7.

The organization leveraged OLTP Compression, Index Prefix Compression, and TCC to improve storage efficiency and optimize performance for large-scale transaction workloads.

As a result, average response time decreased from 4.44 seconds to 0.19 seconds, achieving more than 95% performance improvement.

The case demonstrates how Tibero7 can improve response performance and maintain stable services even under high traffic conditions.

A New Standard for Data Platforms in the AI Era

As enterprise IT environments shift toward AI and cloud-centric architectures, the criteria for selecting a database are changing. Organizations now need to consider not only performance, but also large-scale data processing, high availability, disaster recovery, operational stability, and data utilization.

Tibero7 continues to enhance its core engine and key technologies to meet these evolving requirements.

From performance improvements for large-scale data environments and enhanced HA/DR capabilities to operational safeguards and proven customer deployments, Tibero7 provides a foundation for modern enterprise data platforms.

For organizations evaluating a new DBMS or planning a database upgrade, Tibero7 offers a platform designed to meet the performance, availability, and operational requirements of today’s enterprise environments.
