What do you use to transfer data between nodes in a process model?

To transfer data between nodes in a process model, process variables are used. Process variables act as containers that hold data and can be accessed or modified by different nodes throughout the execution of a process. When a process is in motion, these variables facilitate the passage of information, ensuring that each node can utilize the necessary data from previous steps or pass data along to subsequent steps.

In the context of a process model, variables are crucial for maintaining the state of the process and making decisions based on that state. They allow for dynamic updates to the process as data changes, reflecting the most current information at any point in the workflow.

Other options do serve important functions in Appian but do not directly address the mechanism for transferring data between nodes. Data types define the structure of data but do not facilitate its transfer. Task assignments focus on who is responsible for performing a particular task, rather than how data is communicated across the process. Data storage pertains to the way data is stored externally but does not involve the direct exchange of data between nodes during a process execution.
