What is the primary function of business rules in relation to domain separation?

The primary function of business rules in relation to domain separation is to assign records to domains. This aspect of domain separation is crucial because it enables organizations to manage data accessibility and visibility across different segments or divisions within the business effectively. By using business rules to designate which records belong to which domain, organizations can ensure that users only access information pertinent to their specific domain, maintaining data security and integrity.

This function is fundamental in environments where multiple departments or business units operate independently yet within the same platform. It facilitates organizational structure by aligning data with the correct contexts and ensuring that each domain only sees the information it is intended to access. Without this function, clarity around record management could diminish, leading to potential data mishandling or security violations.
