True or False: Aggregates can have multiple sources, and when entities have relationships, OutSystems automatically creates joins.

The statement is true because aggregates in OutSystems can indeed draw from multiple sources, allowing developers to combine data from various entities within the same aggregate. This is a powerful feature because it enables developers to create comprehensive data views that reflect the relationships between different entities.

When dealing with entities that have defined relationships—such as one-to-many or many-to-many—OutSystems facilitates the process by automatically generating the necessary joins for those relationships. This automation simplifies the development process as developers do not need to manually configure the joins, which can save time and reduce the potential for errors.

The ability to leverage multiple data sources and the automatic handling of joins when relationships exist are core functionalities that enhance data handling within the OutSystems platform, making it easier to query and manipulate relational data effectively.
