Final answer:
Reference data essentials for an organization include the person(s) responsible for the data, the current status of the data, and catalog data. Data breach notifications, while not reference data, are crucial for online privacy and security.
Step-by-step explanation:
When discussing the essential details available in reference data for an organization, several key points are to be considered. These are a. Person(s) responsible for the data, which addresses accountability and data governance within the organization. b. The current status of the data (ex: deployed, approval pending), which provides insights into the lifecycle stage of the data, and c. Catalog data, which is a comprehensive index or a list of data assets held by the organization. However, d. Data breach notifications are not typically considered reference data but are critical for online privacy and security and the organization's response to incidents.
Understanding these details is crucial for maintaining the integrity and security of organizational data. They play significant roles in data management and are a central part of an organization's data governance framework.
