Which data source option should be selected to create a service-backed record?

To create a service-backed record in Appian, selecting the Web Service option is crucial because this approach leverages external services to retrieve data dynamically. A service-backed record is designed to interact with external systems and APIs, allowing for real-time data integration. By using a web service, you can define how Appian will communicate with an external data source, ensuring the record can pull live updates or changes as they occur, which is essential for providing accurate and timely information.

While other options like Database, Connected System, and API may seem relevant, they serve different functions. A database option typically relates to direct database connections for static or pre-defined data rather than dynamically accessing real-time information like a service. Connected Systems can be broader and may include databases, APIs, or other types of data connections; however, they don’t specifically define the service-oriented approach needed for a service-backed record. APIs, while they are critical for integrations, do not directly indicate the method of implementation as a service-backed record would. Therefore, the Web Service option is the most suitable for creating service-backed records.
