What is the main role of the primary domain in domain separation?

The primary domain plays a critical role in domain separation by serving as the main point in the domain hierarchy. This hierarchical structure is essential for organizing and managing multiple domains effectively within an organization. Each domain can represent a distinct area of business or departmental function, and the primary domain acts as a central authority that helps define how these domains interact with one another.

By having a primary domain, it facilitates the control and governance of different domains, ensuring that policies and practices are consistently applied across the entire hierarchy. This structure allows for better management of resources, user access, and data while maintaining clear boundaries that support data separation and security.

While assigning user roles, managing data integrity, and enabling reporting are important aspects of a well-functioning domain environment, these functions are often influenced or regulated by the policies set at the primary domain level. Therefore, the primary domain's role is foundational, providing the essential framework within which the other functions operate effectively.
