Checker Records

Checker Records is a data quality validation module that enforces schema and business rules on tabular datasets. It helps data engineers, stewards, analysts, and QA teams ensure accuracy before reports or migrations. Typical use: customer records before CRM load, product catalogs before analytics ingestion.
\n
Conceptually the tool runs a rules engine per row; you provide dataset, a schema, and a set of constraints; it evaluates each record, flags violations, and aggregates metrics.
\n
Benefits include deterministic checks with explainable error traces, support for batch processing, and clear remediation guidance.
\n
The system supports both standard data quality checks and customizable rules, enabling teams to tailor validation to domain needs. Use cases span data migration, periodic data quality audits, and automated governance checks.
