(also called IDD applications) that are based on subject areas. Recall that a subject area is an implementation of a core entity, such as Person. The subject area organizes and relates the base objects in the MDM
Operational Reference Store
to one another in a three-level tree structure, which makes it easier to manage the data as a unit.
In version 10.0 and later,
Data Director
was modernized. As part of that effort, the data structure changed from subject areas to business entities. A business entity also represents a core entity, but the business entity organizes and relates the base objects in a tree structure with unlimited depth. Business entities support an enhanced user interface, REST API calls, and the ActiveVOS workflow engine for business process workflows.
Review this guide to understand the benefits and differences that come with the business entity data structure. The migration to business entities is optional, but highly recommended. If you choose to migrate an application, follow the instructions to convert to business entities and update workflows.
If an application with subject areas has extensive customization and user exits, carefully weight the pros and cons before beginning a migration.
