Check whether a migrated dataset or Snowflake report matches its source before relying on the results. I will build focused SQL validation checks and document the differences for investigation.

Includes: one source dataset and one Snowflake target dataset or report; up to 10 mapped fields; row-count and control-total checks; duplicate-key and missing-record checks; field-level comparisons for agreed columns; a discrepancy summary; reusable SQL; and one revision.

Please provide the source and target schemas, key fields, mapping rules, an agreed comparison period, and anonymized extracts or approved read-only access. Delivery: within one week after inputs and scope are complete.

This package covers validation of one agreed snapshot. It excludes migration execution, production data changes, pipeline repair, continuous monitoring, warehouse charges, and compliance certification. Findings depend on the supplied data and agreed rules; matching totals alone do not establish full equivalence.
