In the context of an Aggregate, what is the purpose of the Sources section?

The Sources section in an Aggregate is critical because it defines the entities from which the Aggregate retrieves records. When you create an Aggregate in OutSystems, you need to specify which data entities or structures you want to bring into your application. This selection determines the base from which your data will be pulled, allowing for effective data manipulation and retrieval.

In this way, the Sources section serves as the foundation for any queries or operations you want to perform on the data. It allows developers to control which data is accessible and to ensure that the Aggregate pulls the relevant information needed for the application’s logic or UI.

While the other sections of an Aggregate may deal with sorting, filtering, or even displaying outputs, the Sources section distinctly focuses on establishing the origin of the data. This is fundamental before any further operations—like conditions or display settings—can be applied to that data set.
