Which model is used primarily for data that is in motion between systems?

• A. Surrogate key model
• B. Canonical model
• C. Logical data model
• D. Conceptual data model

Answer: (B)

The canonical model is the correct choice for data that is in motion between systems. This model serves as a common standard or format that different systems can use to communicate with each other when exchanging data. The primary purpose of a canonical model is to eliminate the need for each system to understand the internal structure of another system's data, promoting interoperability and reducing integration issues. In environments where data frequently moves between multiple disparate systems—such as in API integrations, data lakes, or service-oriented architecture—a canonical model streamlines the process. It defines a universal language or structure that captures the essential information while masking the individual complexities of each system’s data models. This enables smoother and faster data exchange, enhancing overall system efficiency. Other models mentioned, like the surrogate key model, typically refer to unique identifiers used within a database to represent an underlying entity without exposing its actual value. Logical and conceptual data models are more about representing data structure and relationships rather than facilitating real-time data movement between systems. They focus on organizing and designing the data environment rather than its transit. Thus, the canonical model is uniquely suited to managing the complexities associated with data in motion.
