Which component allows for dynamic display of data based on user inputs and interactions in Appian?

The Interface component is the correct choice because it is designed specifically to create user-facing elements in an Appian application, allowing for dynamic data presentation and user interactions. Interfaces leverage Appian's expression language and design capabilities to respond to user actions in real-time. This means that when a user inputs information or interacts with various interface elements, the display of data can change immediately based on those interactions, leading to a more engaging and responsive user experience.

For example, an interface might allow users to select options from a dropdown menu, and based on their selection, different data sets could be displayed or hidden. This level of interactivity is fundamental in creating applications that are both user-friendly and functional, enabling users to achieve their tasks effectively.

The other options, while important components of the Appian platform, do not provide the same level of dynamic interaction with the user. The Data Store is primarily concerned with data storage and management; the Process Model focuses on automating business processes; and Integration is used to connect Appian to external systems or services. These components play vital roles in the overall functionality of an Appian application, but they do not inherently facilitate the dynamic display of information based on user interaction the way Interfaces do.
