# Schema & Key Analytics

**Your schema, under surveillance.**

Continuous monitoring of your data's shape. DataHarbor learns schema over time and surfaces emerging risks automatically.

## How it works

As Virtual APIs are used, DataHarbor:

1. **Learns** schema shape over time
2. **Detects** schema drift as new fields appear
3. **Flags** uncovered keys that may contain sensitive data
4. **Identifies** risky combinations that enable re-identification
5. **Surfaces** compliance violations

## Schema drift detection

When your upstream API adds new fields, DataHarbor notices. New fields are **not automatically protected** — you receive an alert to review and apply appropriate controls.

## Uncovered key detection

DataHarbor flags fields that may contain sensitive data but have no controls applied.

## Risky combination detection

Some field combinations enable re-identification even when individual fields seem safe. DataHarbor identifies these patterns — for example, the combination of zip code, date of birth, and gender can identify 87% of the US population.

## Compliance detection

Automatic detection of potential compliance violations:

| Regulation        | Detection                                   |
| ----------------- | ------------------------------------------- |
| GDPR Article 4(1) | Personal data exposed without consent basis |
| CCPA              | California resident PII without disclosure  |
| HIPAA             | PHI fields without BAA coverage             |

## Dashboard view

The Schema Analytics dashboard shows:

* **Schema coverage**: Percentage of fields with controls applied
* **Risk score**: Aggregate risk based on uncovered and risky fields
* **Field inventory**: Complete list of observed fields with control status
* **Alert history**: Timeline of detected issues
