Which of the following is one of the three data objects in Appian?

• A. Process Variables
• B. Node Inputs and Outputs
• C. Interface Inputs
• D. Data Stores

Answer: (A)

Process Variables are the in‑process containers that hold values as a process runs. They are one of the three data objects Appian uses to model data across an application: Process Variables, Data Stores, and Interface Inputs. A process variable is created in a process model and can be read, written, and passed between nodes, so it’s the primary way data moves through a workflow. Node inputs and outputs are specific to individual nodes and don’t serve as the global data container for the process; Interface Inputs define what data an interface expects rather than what the process itself stores and carries; Data Stores provide persistent, database-backed storage rather than in‑flight process data. Because the item is a process‑level data container, it’s the best choice.
