Which of the following statements about the foundation of OneStream artifacts is true?

• A. Metadata is the foundation on which all application artifacts are built.
• B. Dashboards are the foundation on which all application artifacts are built.
• C. Rules are the foundation on which all application artifacts are built.
• D. Mapping Rules are the foundation on which all application artifacts are built.

Answer: (A)

The foundation being tested is metadata. In OneStream, metadata defines the data model: the dimensions, their members, hierarchies, and the core elements like accounts, entities, versions, currencies, and scenarios. All other artifacts are built to operate against this model. Rules perform calculations based on the defined members, mapping rules translate incoming data into the metadata-defined structure, and dashboards present data that is organized by that same metadata. Because everything hinges on this underlying metadata structure, it is the true foundation for all application artifacts. Dashboards, rules, and mapping rules are important, but they rely on the metadata instead of forming the base themselves.
