# ETL Testing & Data Quality Assurance

ETL Testing & Data Quality Assurance

Automated ETL testing, data pipeline validation, source-to-target reconciliation, and data quality assurance at enterprise scale.

## The ETL Testing & DQA Advantage

Bad data costs organizations an average of $12.9M annually. DataTrust prevents it.

Move from manual ETL testing to automated data pipeline validation and quality assurance with continuous monitoring and reconciliation.

## Why Traditional ETL Testing Falls Short

Manual ETL testing and basic validation can't keep up with modern data pipeline complexity

✕ Manual ETL testing that can't scale with pipeline changes  
✕ Silent transformation failures discovered too late  
✕ No visibility into data pipeline health  
✕ Regression issues after every deployment  
✕ Incomplete coverage across ETL jobs  
✕ No automated anomaly detection in pipelines

## Source-to-Target Reconciliation at a Glance

DataTrust validates data accuracy by comparing source records against target systems. Our intelligent matching handles row-level, aggregate, and balance validations with automatic variance detection.

- Row-by-row comparison with transformation support  
- Aggregate totals and balance checks  
- Automatic variance detection and reporting  
- Cross-platform reconciliation support
