Master Data Management Overview

Master Data Management (MDM) in Qarion lets you create, version, and govern authoritative reference datasets directly inside your governance platform — no external spreadsheets or ad-hoc databases needed.

What is Master Data?​

Master data refers to the core business entities that are shared across systems: country codes, product hierarchies, cost centers, customer segments, and similar reference lists. Keeping this data accurate, versioned, and governed is essential for consistent reporting and analytics.

Key Capabilities​

Dataset Creation​

Create a new dataset from the Master Data section in the sidebar:

  1. Click New Dataset
  2. Provide a name and optional description
  3. Define the initial schema (columns and types)
  4. The dataset starts in Draft status

Dataset List​

The master data landing page shows all datasets in the current space:

  • Name and description
  • Current version number
  • Status (draft / published)
  • Last modified timestamp
  • Quick actions: open, export, delete

Spaces Integration​

Datasets are scoped to spaces — the same space-based access model used for data products, quality checks, and governance processes applies here.

How It Works​

┌──────────────┐     ┌──────────────┐     ┌──────────────┐
│    Draft     │────▶│   Publish    │────▶│  Version N   │
│  (editable)  │     │  (snapshot)  │     │  (immutable) │
└──────────────┘     └──────────────┘     └──────────────┘
       ▲                                         │
       └─────────── New Draft ◀──────────────────┘

Each publish creates a point-in-time snapshot with a version number. Previous versions are always accessible for comparison and audit.
