Integrating SQL Server 2022 with Microsoft Purview

Costa Rica

Microsoft Purview SQL Server 2022

Last updated: 2025-07-17

Microsoft Purview provides a unified data governance solution that enables organizations to manage and govern their on-premises, multi-cloud, and software-as-a-service (SaaS) data. Integrating SQL Server 2022 with Purview allows you to discover, classify, and manage sensitive data, enforce compliance, and monitor data usage across your organization.

How to Integrate SQL Server 2022 with Purview

Registering the SQL Server Database in Purview

  • Go to the Microsoft Purview Studio.
  • Navigate to Data Map > Register > SQL Server.
  • Provide the required connection details (server name, authentication, etc.).
  • Set up a scan rule set to define what metadata and classifications to extract.
  • Schedule regular scans to keep metadata and classifications up to date.

Enabling Unity Data Governance

  • Use Unity Catalog within Purview to manage access policies, data lineage, and data sharing.
  • Assign roles such as Data Owner, Data Steward, and Data Consumer to control access and responsibilities.
  • Track data movement and transformations for compliance and auditing.

Data Classification and Labeling

  • Apply built-in or custom classifiers to automatically detect and label sensitive data (e.g., PII, financial data).
  • Use labels to drive downstream policies such as Data Loss Prevention (DLP) and access controls.

Managing DLP (Data Loss Prevention) Projects

DLP projects in Purview help you identify, monitor, and protect sensitive data within your SQL Server databases.

E.g: DLP Policy for Customer PII (Click to expand)

Prevent unauthorized export of customer personally identifiable information (PII).

Steps:

  1. Create a DLP Policy: In Purview, define a policy targeting tables/columns with PII (e.g., email, SSN).
  2. Define Detection Rules: Use built-in or custom classifiers to identify PII fields.
  3. Set Actions:
    • Alert data owners when PII is accessed or exported.
    • Optionally, block export or require additional approval for sensitive data.
  4. Monitor and Audit: Use Purview’s monitoring dashboard to track policy violations and data access patterns.
E.g: DLP Policy for Financial Records (Click to expand)

Prevent unauthorized access or leak of payroll, tax records, and bank account data.

Steps:

  1. Create a DLP Policy: Target tables like Payroll, Invoices, or TaxDocuments.
  2. Define Detection Rules: Use financial classifiers to detect fields like account_number, routing_number, salary, etc.
  3. Set Actions:
    • Mask fields for non-authorized users.
    • Trigger real-time alerts for exports or downloads.
  4. Monitor and Audit: Audit trail of accesses to sensitive financial information.
E.g: DLP Policy for Intellectual Property (IP) (Click to expand)

Protect proprietary formulas, product designs, or source code stored in SQL Server.

Steps:

  1. Create a DLP Policy: Focus on R&D tables like ProductDesign, AlgorithmSpecs, or Blueprints.
  2. Define Detection Rules: Customize classifiers using keywords or phrases tied to internal IP.
  3. Set Actions:
    • Block queries from external users or consultants.
    • Require dual-approval for exports or backups.
  4. Monitor and Audit: Flag and investigate unusual access patterns.
E.g: DLP Policy for Healthcare Data (HIPAA) (Click to expand)

Comply with healthcare regulations by securing patient records and medical history.

Steps:

  1. Create a DLP Policy: Target tables containing diagnosis_codes, treatment_notes, or insurance_info.
  2. Define Detection Rules: Enable built-in classifiers for HIPAA-related entities such as Patient ID, Diagnosis, Prescriptions.
  3. Set Actions:
    • Encrypt or mask records during query outputs.
    • Notify compliance officers of any unauthorized attempts.
  4. Monitor and Audit: Include incident tracking for audits and regulatory reporting.

Cost Management and Budgeting

Microsoft Purview Account:: Billed per vCore-hour and per GB of data processed during scans. The pricing structure is based on:

  • Data Map (capacity units, always-on)
  • Scanning (pay-as-you-go, based on vCore usage and scan duration)
  • Managed Virtual Network and API/Data Transfer costs for cross-cloud governance
  • Resource Set Processing (based on processing time)

Best Practices

  • Automate Scans: Schedule regular scans to keep metadata and classifications current.
  • Least Privilege: Assign only necessary permissions to users and service principals.
  • Monitor Usage: Regularly review Purview dashboards for unusual activity or policy violations.
  • Review Costs: Monitor Purview and SQL Server usage to optimize resource allocation and control expenses.

Integration with Purview for Unity Catalog

SQL Server 2022 can be integrated with Microsoft Purview to enable a Unity Catalog for data governance and management. This integration allows you to:

  • Discover and classify sensitive data.
  • Track data lineage across your SQL Server databases.
  • Enable centralized data governance.

Steps to Integrate

  1. Register the SQL Server Database:
    • Navigate to the Microsoft Purview portal.
    • Register your SQL Server 2022 as a data source.
  2. Scan the Data Source:
    • Configure scanning rules to classify and catalog the data.
    • Schedule periodic scans to keep the catalog updated.
  3. Manage Data Lineage: Use Purview to visualize data lineage across your SQL Server databases.
  4. Set Up Access Policies: Define access policies for data governance using Purview.

Benefits

  • Enhanced data discovery and classification.
  • Improved compliance and governance.
  • Centralized management of data assets.
