🔬 Monitor data quality with Notion rules, SQL checks & AI-powered alerts
⚡ 186 views · 🔬 Document Extraction & Analysis
Description
Description
This workflow continuously validates data quality using rules stored in Notion, runs anomaly checks against your SQL database, generates AI-powered diagnostics, and alerts your team only when real issues occur.
Notion holds all data quality rules (source, field, condition, severity). n8n reads them on schedule, converts them into live SQL queries, and aggregates anomalies into a global run summary.
The workflow then scores data health, creates a Notion run record, optionally opens a Jira issue, and sends a Slack/email alert including AI-generated root cause & recommended fixes.
Target users
Perfect for:
- DataOps
- Analytics
- Product Data
- BI
- Compliance
- ETL/ELT pipelines
- Platform reliability teams.

How it works
-
Notion → Rules Database Each entry defines a check (table, field, condition, severity).
-
n8n → Dynamic Query Execution Rules are converted into SQL and checked automatically.
-
Summary Engine Aggregates anomalies, computes data quality score.
-
AI Diagnostic Layer Root cause analysis + recommended fix plan.
-
Incident Handling Notion Run Page + optional Slack/Email/Jira escalation. Silent exit when no anomaly = zero noise.
Setup Instructions
- Create two Notion databases:
-
Data Quality Rules → source / field / rule / severity / owner image.png
-
Data Quality Runs → run_id / timestamp / score / anomalies / trend / AI summary/recommendation image.png
-
- Connect SQL database (Postgres / Supabase / Redshift etc.)
- Add OpenAI credentials for AI analysis
- Connect Slack + Gmail + Jira for incident alerts
- Set your execution schedule (daily/weekly)
Expected outcomes
- Fully automated, rule-based data quality monitoring with minimal maintenance and zero manual checking.
- When everything is healthy, runs remain silent.
- When data breaks, the team is notified instantly: with context, root cause insight, and a structured remediation output.
