What type of business data models can be shared across multiple systems?

Business data models are essential frameworks that define how data is organized, stored, and accessed within an organization. They establish a common understanding of data across various stakeholders, ensuring consistency and clarity in the way data is used and interpreted.

The correct answer focuses on the concept that business data models are specifically designed to be shared across multiple systems. These models provide a structured representation of a company’s data, enabling different applications, departments, or even organizations to align with a standard set of definitions and relationships. This interconnectivity allows businesses to seamlessly share data, facilitating better communication and streamlined operations.

In contrast, single system models are tailored for a specific system and lack the versatility required to be applicable across multiple platforms. Physical models, while important in the context of database design, pertain more to the technical aspects of database implementation and structure rather than the high-level conceptualization that business data models provide. Therefore, it is the business data models that stand out as the correct choice for sharing data across various systems.
