Final answer:
The Reference data model depicts the functions and structure of a system or entity, facilitating effective design and implementation.
Step-by-step explanation:
The Reference data model depicts the functions of a system or entity. It serves as an abstract representation of the different aspects related to the design, including equations, physical representations, computer representations, and other representations. The model helps in understanding how the system works and how different components interact with each other.
For example, in the context of a database management system, the Reference data model would describe the structure and relationships between tables, entities, attributes, and the rules governing data integrity and access. It provides a clear overview of the system, making it easier to implement and maintain.
In summary, the Reference data model helps in visualizing and understanding the functions and structure of a system or entity, facilitating effective design and implementation.
