🧭Data Onboarding

NEW

The process of ingesting, validating, and aligning new data sources into existing systems.

DESCRIPTION

Data onboarding introduces new sources to a platform by assessing schemas, mapping fields, and establishing ingestion pipelines. It includes data profiling, validation rules, and reconciliation to ensure fitness for use. Contracts and SLAs guide expectations and changes. Automation and templates accelerate repeatability and reduce errors. Effective onboarding produces documentation, lineage, and monitoring for ongoing reliability.
