Managing master data with Master Data Management (Beta)

The Master Data Management (Beta) service on IBM Cloud Pak for Data as a Service enables you to consolidate data from the disparate sources that fuel your business to establish a single, trusted, 360-degree view of your customers.

The Master Data Management service includes two connected and complementary user experiences:

  • Master data configuration for data engineers to prepare and configure master data. This experience includes:
    • Configuring the master data system.
    • Refining the generated data model.
    • Uploading or connecting data sources.
    • Mapping data into the model.
    • Running Master Data Management service’s powerful matching capability to create master data entities.
    • Configuring and tuning the matching algorithm to meet your organization’s requirements.
  • Master data explorer for business analysts and data stewards to search, view, analyze, edit, and export master data entities and records.

Restriction: The Master Data Management Beta Lite plan allows you to create one service instance per account and process up to one million records. Beta Lite plan services are active for 60 days or until the beta period is over, whichever comes first. Lite plan services will be deleted after 30 days of inactivity.
