Instead of waiting for the ETL job to finish and then running a manual "Check," we implemented a Data Virtualization (DV) auditing layer using TIBCO (CIS/TDV).
1. PUSHDOWN AUDIT LOGIC
We used Pushdown Optimization to send validation queries directly to the source and target systems simultaneously.
- The Process: The DV layer compares the source "Source of Truth" with the target "Loaded Data" in real-time.
- The Benefit: We identified data truncation, type mismatches, and missing records before the business users accessed the dashboards.
2. AUTOMATED DATA RECONCILIATION
We architected a "Virtual Audit View." This view performed a Semijoin between the source and target keys to highlight orphans (records that failed to load) without moving millions of rows into a middle-tier server.
THE RESULT: 100% DATA CERTAINTY
By moving from manual sampling to automated, virtualized auditing:
- Identification Time: Errors were caught in minutes, not days.
- Operational Efficiency: Reduced the need for "Data Fix" tickets by 40%.
- Trust: Engineering and Finance teams gained 100% confidence in the automated pipelines.
I help enterprises build "Self-Auditing" data ecosystems.
- ETL/ELT Auditing: Real-time validation of your data pipelines.
- Compliance Frameworks: Ensuring data integrity for global standards.
- Virtualization Strategy: Implementing TDV and IBMDV for proactive monitoring.
