Do aggregates support multiple source entities?

Aggregates in OutSystems are designed to retrieve and manipulate data from one or more entities within the application’s database. The correct answer indicates that aggregates can indeed support multiple source entities. This capability allows developers to create complex data queries that combine data from different entities, which is particularly useful for scenarios where information from various data sources is needed for reporting, dashboards, or combined user interactions.

By utilizing multiple source entities within an aggregate, developers can easily join entities or combine data conditions to tailor the data set to meet specific requirements. This flexibility enhances the power of aggregates in handling more sophisticated data retrieval and manipulation tasks without needing to write complex SQL queries manually.

While the other options might suggest limitations or conditions where aggregates cannot utilize multiple entities, the design and functionality of OutSystems enables the use of multiple source entities in a straightforward manner. Thus, the answer that asserts aggregates can always handle multiple source entities captures the full potential of this feature in OutSystems.
