Which object defines the structure of data entities and relationships in the Metadata API?

• A. Data Models
• B. Calculated Insights
• C. Data Lakes
• D. Activation Targets

Answer: (A)

In metadata terms, how data is organized—the entities, their attributes, and how they relate to one another—is captured by data models. Data models define the structure of each entity (like attributes and types) and the relationships between entities (such as one-to-many or foreign key links). This is exactly what a Metadata API uses to describe how data is arranged, enabling consistent understanding, querying, and governance of the data landscape. Calculated insights describe derived metrics, data lakes are storage repositories for raw or processed data, and activation targets are destinations or endpoints for pushing data for use. Data models, by defining the schema and relationships, best explain the structure the API represents.
