Which of the following best describes the purpose of the 'Connection' interface?

The 'Connection' interface primarily serves as a means to model systems within SAP Analytics Cloud. This interface is designed to establish a seamless link between the data sources and the analytic functionalities within the platform. It facilitates the integration of different systems, allowing users to access and manipulate data effectively for analytic purposes.

By modeling systems, users can create a structured approach to how data is accessed and analyzed, ensuring that insights can be drawn from various data sources in a coherent and organized manner. This function is crucial for harnessing the power of analytics, as it allows businesses to leverage their data in a way that is meaningful and aligned with their analytical frameworks.

In contrast, the remaining choices focus on concepts that do not fully capture the primary purpose of the 'Connection' interface. While linking data with external platforms, storing data products, and creating dashboards are important functionalities within the broader context of SAP Analytics, they are not the defining role of the 'Connection' interface itself.
