Master Data Management (MDM) is crucial for financial services, but even with robust tools like Reltio, data inconsistencies can arise, introducing regulatory risks and undermining decision-making. Financial institutions often struggle with ensuring proper data reconciliation before ingestion, leading to data mismatches that impact key operations. Comprehensive data observability can flag inconsistencies, while full transparency into data lineage is necessary to reduce compliance risks. Additionally, visibility inside MDM systems like Reltio is essential to proactively detect and resolve quality issues in real-time, without relying on manual extraction and reconciliation. By addressing these pitfalls with enterprise-grade data observability, financial institutions can ensure their data is compliant, accurate, and fraud-proof.
