Final answer:
In software workflows, data from an action is stored in variables or databases to be available for subsequent actions, with the use of temporary storage like session data or cache in some cases.
Step-by-step explanation:
When working with workflows in a software application or development environment, the data from an action is typically stored in variables or sometimes within a database so that it can be accessed by subsequent actions. Variables act as placeholders or containers for information that can be used and modified throughout the flow of a program or process. These can be predefined or dynamic, and the scope of the variable will determine where it can be accessed from within the flow. To maintain data across different steps of a flow, the content of a variable may be updated or a new variable may be defined to hold the new data. Some platforms may also use other forms of temporary storage, like session data or cache, depending on the complexity and requirements of the workflow.
