The Sources section of an Aggregate is used to do what?

The Sources section of an Aggregate is crucial for defining the entities from which you want to retrieve the records. When you create an Aggregate in OutSystems, you are typically interested in collections of data that come from specific data models, which are represented by entities. By selecting these entities in the Sources section, you are essentially giving the Aggregate the context it needs to understand where to pull the data from, ensuring that the records returned are directly related to the specified entities in your application's database.

This section acts as the foundational step for establishing data sources for the Aggregate, facilitating further operations such as filtering, sorting, or manipulating the data. While other functionalities, such as setting values, defining conditions, or ordering output records, are also possible within an Aggregate, they depend on the entities specified in the Sources section to function correctly. This linkage highlights the importance of choosing the right entities for accurate data retrieval.
