Which of the options describes records best in Appian?

Records in Appian are best described as data sources that are aggregated for user interaction. This means that they provide a structured method for users to view and interact with data across different contexts within the application. Records serve as a versatile interface for presenting information, allowing users to compile, filter, and access data from various sources in a coherent manner.

In Appian, records can display not only static data but also dynamic information which can be manipulated based on user input or real-time data changes. This capability highlights the importance of user interaction, as records facilitate decision-making processes by presenting relevant data from different business systems in a user-friendly and accessible format.

The other options do not accurately represent the functionality and purpose of records in Appian. While a live display of application metrics may pertain to certain dashboard features, it does not encompass the broader data interactions that records are designed for. Similarly, a catalog of available user roles focuses on user permissions rather than data aggregation, and an administrative tool primarily pertains to management functions instead of directly engaging users with data. Thus, the option that emphasizes the aggregation of data for user interaction accurately captures the essence of what records are in Appian.
