Which statement about the use of perspectives is true?

The statement that at least one perspective needs to be defined first is accurate because perspectives serve as a framework or context for analyzing and interpreting data within a system. In order to extract relevant insights or perform analyses, there must be a clear viewpoint or lens through which the data is viewed. Defining at least one perspective establishes the criteria and parameters for how data is organized and presented, enabling users to work effectively within the system.

Without having at least one perspective defined, the framework necessary for analysis becomes unclear, leading to potential confusion and inefficiencies in data utilization. This requirement ensures that any analyses or reports generated are based on a structured context, which is essential for making informed decisions and interpretations based on the data. The inability to operate within a defined perspective would hinder the functionality and utility of the data management system.
