Database Data Accuracy Validation - 01/07/2026 03:13 EDT
Budget: $8 – $15 CAD
I need a precise, methodical review of the data held in our production databases to confirm every record is accurate. The assignment is limited to accuracy checks—completeness and consistency are out of scope—so I expect you to zero-in on incorrect values, mismatched formats, and any figures that fail to meet predefined business rules.
Here is what I’ll provide once we start: secure, read-only access to the database, a short data dictionary, and the list of critical tables and fields that drive our dashboards. Your task is to analyse those tables, flag inaccuracies, and deliver a concise report describing each issue, how you identified it (SQL, Python, BI tool, etc.), and a recommendation to fix or prevent it.
Acceptance criteria
• All critical fields scanned for accuracy issues
• A reproducible script or query set included
• A final summary report highlighting problems and recommended remediation steps
If you have strong SQL skills and experience validating large datasets, I’m ready to get this moving quickly.
