Which of the following would be an allowable step in a process model?

Filling out a form is indeed an allowable step in a process model because it directly engages users in data entry, which is often a fundamental component of a business process. In process modeling, filling out forms is typically used in user tasks, enabling interaction between the system and the user where specific inputs are captured for further processing.

The other options, while related to data management and processing tasks, do not fit as user-facing steps in a process model in the same way. Changing field values for a record is a backend action that does not involve direct user input. Querying a record type or data store entity typically occurs in the background as part of data retrieval but does not constitute an active step performed by a user in the process. Similarly, saving data to a database is an implementation detail that occurs behind the scenes, often handled by the system rather than a direct interaction by the user.

The focus on user engagement through filling out forms highlights the importance of involving users directly in the workflow, which is essential for effective process modeling.
