The life insurer operated on an aging data integration setup that restricted analytical responsiveness and created operational friction:

‍

• Severe Turnaround Lags: Operational reporting was hindered by source system delays ranging from day-end processing to T-2 lag, limiting the speed of operational and strategic decision-making.

• Batch-Constrained Architecture: Legacy infrastructure could only ingest data in rigid batch windows, offering no capability to stream changes or pull data on demand as transactions occurred.

• Manual Operational Overhead: Core business logic was distributed across disparate SSIS packages and custom stored procedures, resulting in protracted release cycles, elevated maintenance costs, and increased vulnerability to human error.

‍

We engineered an automated, low-overhead data integration ecosystem that unifies transactional Oracle databases with analytical data warehouses using real-time capture and automated design patterns.

‍

Key capabilities include:

‍

• Pre-Configured Oracle Connectivity: Established dedicated, secure endpoint connections across source and target Oracle platforms with all required environment prerequisites configured for optimal throughput.

• Simplified CDC Lifecycle Management: Implemented Qlik Replicate to streamline the creation, monitoring, and ongoing maintenance of real-time Change Data Capture jobs without requiring intrusive software agents on source nodes.

• Multi-Pattern Extraction Framework: Validated and configured three distinct extraction methodologies within the PoC scope to match specific source table behaviors - Extraction based on dynamic SQL queries, Extraction based on database Procedures and Functions, Extraction based on Materialized Views.

• Automated Warehouse & Mart Generation: Utilized Qlik Compose to transform legacy SSIS and stored procedure logic into automated staging tables, auto-generating the underlying ETL code required to populate downstream data marts.

• Continuous Ingestion Workflows: Deployed integrated tasks that autonomously execute full historical loads before switching to continuous, low-impact CDC operations.

‍

Deploying the real-time CDC and automated data warehousing solution delivered immediate performance gains and operational cost reductions:

‍

• Real-Time Data Availability: Eliminated historical T-2 data delays by streaming source updates directly to analytical databases as transactions occur.

• Automated Full Load and CDC Switch: Enabled unified tasks that complete historical bulk loads and automatically transition to real-time change tracking without manual intervention.

• Risk & Cost Reduction via Auto-Generated ETL: Replaced manual coding with auto-generated ETL structures, dramatically reducing engineering hours, bug rates, and maintenance overhead.

• Streamlined Data Warehouse Modeling: Standardized data mart and staging creation, enabling fast incorporation of new business logic and regulatory reporting rules.

• High-Performance Database Replication: Achieved superior replication performance between Oracle environments while eliminating processing overhead on operational source databases.

Looking Ahead

By migrating from manual batch extraction to an automated, real-time replication framework, this IRDAI-regulated life insurer has established a future-ready analytical backbone. As data volumes expand, this scalable architecture provides the high-velocity foundation required to deploy real-time actuarial risk modeling, automated fraud detection across claims processing, and responsive self-service customer portals—ensuring continuous compliance and operational agility.
