Domains & Categories

Introduction to Domains & Categories


A domain is said to be a high-level business unit of an organization. An organization can have multiple high-level entities and, therefore, multiple domains. Each domain and its hierarchy is defined independently of other domains in which business entities like Data assets, Business Glossaries, PII are defined. 

For each domain, the hierarchy could be defined as Categories that resonate with divisions/subdivisions / departments usually organized around business functions like sales, marketing etc.,

Domains are used to categorize the organization's data assets that help in configuring the classifications, and categories and to maintain the business glossary terms. They also play a very important role in setting up Data Quality Rules and Certification Policies.

Areas of Use

In OvalEdge, domains are created and used for the below 

  • Business glossary terms
  • Data asset group tags-DAG tag ( similar data objects grouped, and organized to share the ownership and stewardship different than one configured at schema level)
  • Data Classifications(configure data classifications for compliance in a domain)

Domain Management

Each domain created must have by default a steward, and a reviewer who can manage the domain level terms. There can be optional steward & reviewer assigned at a category level who can manage the category level terms.

For more details on the user role permissions, See this article Roles and Permissions on a Domain.


The default definition of a domain steward is one who is responsible to maintain the definitions and business context of a suggested term and finally publish the term. 


The default definition of a domain reviewer is one who is responsible to review the suggested term and its definition and the business context of the term.
