What type of data does the Process Design Engine store?

The Process Design Engine is primarily responsible for the storage and management of information related to the design of process models within Appian. This includes the configurations that dictate how processes are structured and behave, such as defined flows, user actions, and overall business logic.

When a developer creates or modifies a process model, this design information encompasses various elements such as entities, linked data, decisions, and the various task configurations needed to ensure the process executes as intended. The Process Design Engine allows for systematic versioning and management of these process design artifacts, ensuring that processes can be efficiently updated and maintained throughout their lifecycle.

In contrast, while the other options do relate to aspects of application configuration or user interaction within Appian, they do not fall under the specific purview of the Process Design Engine. Document metadata and settings pertain to file handling and storage, user profile details are related to individual user accounts and roles, and notification settings concern how and when users receive alerts or messages regarding process activities. Therefore, they are managed by different components of the Appian platform rather than the Process Design Engine itself.
