In which areas can interfaces be implemented in applications?

The choice of forms and record lists as the correct answer highlights the versatility of Appian's interface capabilities. In Appian applications, interfaces are primarily focused on user interactions and the presentation of data.

Forms allow users to enter and manipulate data, making them essential for collecting input from users. They can include various components like text fields, dropdowns, checkboxes, and more, enabling a rich interactive experience.

Record Lists, on the other hand, present collections of related data to users, often in a tabular format. This allows users to view and interact with multiple records at once, fostering efficient data management. Interfaces can be used within record lists to display detailed information about each record, as well as actions that users can perform on them.

This choice accurately reflects areas where user interaction and data presentation are critical, showcasing the broad applicability of interfaces in creating responsive and engaging applications. The other areas mentioned, while important in the Appian environment, do not primarily focus on user interaction in the same way forms and record lists do.
