Bridging Legacy and Modern: Enabling Real-Time Enterprise Data Integration
Bringing Real-Time Data from Mainframes and Beyond
  • March 17, 2026

In today’s digital economy, real-time data is no longer optional — it is essential. Organizations rely on timely insights to power analytics, dashboards, AI models, and cloud applications.

However, many enterprises still run their most critical workloads on mainframe systems such as VSAM, DB2 for z/OS, and IMS — alongside modern databases like Oracle, SQL Server, Cassandra, and various cloud platforms.

This raises a key question:

How does enterprise data move from legacy systems to modern analytics platforms in near real time?

The Role of Change Data Capture (CDC)

Change Data Capture (CDC) is the technology that makes this possible.

Instead of copying entire databases repeatedly, CDC captures only what has changed — inserts, updates, and deletes — and streams those changes continuously to target systems.

Source Systems

Simple Architecture Flow

Source Systems (Mainframe / DB2 / IMS / VSAM / Oracle / SQL Server / Cloud Databases)

CDC Engine

Kafka / Data Warehouse / Cloud Platforms / Streaming Applications

This approach ensures efficiency, speed, and minimal system impact.

Why Enterprise CDC Tools Matter

Modern enterprise CDC tools — such as IBM InfoSphere Data Replication (IIDR) — read native database logs directly.

This enables:

  • Commit-level transactional consistency
  • Minimal impact on source systems
  • Advanced filtering, transformation, and data mapping
  • Near real-time replication to distributed and cloud platforms
  • High availability with automatic restart and recovery

These capabilities ensure reliable, scalable, and secure data movement across enterprise environments.

Other CDC Platforms Supporting Mainframes

Several leading CDC platforms support mainframe and distributed data sources, including:

  • Qlik Replicate
  • Oracle GoldenGate
  • Precisely Connect
  • Rocket Data Replicate & Sync

Each platform provides powerful capabilities for integrating legacy and modern ecosystems.
