The Challenge
The Hidden Data Quality Crisis in Public Health Systems
Health departments operate some of the most data-intensive environments in government — yet most quality issues go undetected until they affect public reporting, federal compliance, or executive decision-making.
Dashboards Show Wrong Numbers
Executives and public health directors make decisions based on BI dashboards — but nobody is verifying those numbers against the source database. The "last-mile" gap between data and display is invisible to most tools.
Bad Files Enter the System
Incoming data files from labs, providers, and federal systems are loaded without validation — introducing schema mismatches, null values in mandatory fields, and format errors that propagate through the entire data model.
Pipeline Failures Go Undetected
ETL jobs complete without errors while silently loading corrupted, duplicate, or incomplete records into clinical and operational systems. Monitoring shows green. The data is wrong.
Business Rules Are Not Enforced
Critical logic — "patient_id must exist in the registry", "case counts cannot decrease", "reportable conditions require a jurisdiction code" — exists in documentation but is not systematically tested in production data.
The Solution
Vexdata for Health Departments
Six capabilities deployed for the Massachusetts Department of Public Health and designed to scale to any state or local health system.
1
Dashboard Data Quality Testing
Vexdata programmatically extracts visual values from your BI dashboards and compares them against SQL-derived ground truth from the source database — ensuring the numbers your executives and public health directors see are exactly what is in the data. This eliminates the last-mile validation blind spot that no other data quality tool addresses.
2
End-to-End Pipeline & ETL/ELT Validation
Row count, schema, data type, referential integrity, duplicate, and null-check validations across every layer of your health data infrastructure — RDBMS, cloud warehouses, data lakes, flat files (CSV, Parquet, JSON), and APIs — with native hooks into the orchestration tools your team already uses.
3
Business Rule Validation
Codify the clinical and operational logic that governs your data — "patient_id must exist in the master registry", "case counts cannot retroactively decrease", "reportable conditions require a valid jurisdiction code" — as reusable, versioned rules executed automatically across environments and time periods.
4
Incoming File Validation
Every file arriving from labs, providers, insurers, federal systems, and partner agencies is validated at the point of entry — before it touches your systems. Schema compliance, field completeness, format integrity, and business rule conformance are checked automatically. Bad data is quarantined, not loaded.
5
Dashboards for Every Persona
Purpose-built views for each stakeholder in the health department — data engineers see pipeline health and validation detail, data analysts see record-level quality scores, and department directors see executive summaries with trend lines and compliance status. The right information for the right person.
6
Enterprise Integrations
Vexdata connects directly into your existing notification and workflow infrastructure. Data quality alerts route to the right team through the tools they already use — no new processes required, no new dashboards to check.
Whom it is for
The Right View for Every Role
Health departments have diverse stakeholders. Vexdata's persona dashboards surface the right information for each one — without requiring everyone to navigate a technical monitoring tool
The Challenge
How it works
From Connection to Continuous Quality
Vexdata deploys in days — not months — and integrates with your existing data infrastructure without requiring schema changes or pipeline rebuilds
Connect Your Sources
Connect Vexdata to your databases, data warehouses, BI tools, file feeds, and APIs. Native connectors for 50+ source types — no custom engineering required.
Define Your Rules
Configure validation rules, business logic, schema expectations, volume thresholds, and freshness SLAs through a no-code rule builder — or import from existing documentation.
Run Automated Validation
Vexdata validates on every load, on every incoming file, and continuously in production — surfacing issues at the earliest point in the pipeline, not after they reach consumers.
Act on Results
Alerts route to email, Teams, Slack, or Jira. Validation reports are audit-ready for federal compliance. Dashboards give every persona the view they need.
Real-World Impact
What Health Departments Can Expect
Validated outcomes from automated data quality and pipeline validation — eliminating the reactive fire drills that consume data engineering capacity
