GLOSSARY

The ability to understand and diagnose the health, behaviour, and reliability of data across pipelines and platforms using metadata and telemetry.

Data observability reduces the time that broken or stale data affects reporting, automation, customer experiences, and AI systems.

A platform detects an unexpected fall in daily order volume, traces it to a changed source schema, identifies affected dashboards, and verifies the repaired backfill.

Observability does not define whether data is semantically correct or fit for every purpose. Poor thresholds create noise, and coverage depends on accessible metadata, lineage, and ownership.

It monitors dimensions such as freshness, volume, schema, distribution, quality, lineage, and pipeline performance. Alerts and dependency context help teams identify anomalies, locate root causes, assess downstream impact, and verify recovery.
