You need to be able to define record type relationships. What is a required prerequisite in Appian?

To define a relationship between two record types in Appian, both record types must have data sync enabled. This is a fundamental prerequisite because relationships leverage Appian's in-memory data fabric to perform fast and efficient joins and queries across related data sets. Enabling data sync copies the source data into Appian, allowing the platform to manage, index, and relate the data without repeatedly querying the external source, which is essential for the performance of record-powered applications.

B. The record types must be on a virtualized data source.

This is incorrect. Relationships require synced data. Data virtualization is the alternative to data sync, where Appian queries the source system directly for each request.

C. The record types must be stored in the local Appian business database.

This is incorrect. The source of the data can be an external database. The critical requirement is that data sync is enabled for the record type, not the physical location of the source data.

1. Appian Documentation: Record Type Relationships.

Reference: In the "Prerequisites" section, the documentation explicitly states: "To establish a relationship between two record types, both record types must have data sync enabled." This confirms that data sync is a mandatory prerequisite for creating relationships.
