What role does a 'Page List' property play in managing '1-to-many' relationships?

A 'Page List' property is essential in managing '1-to-many' relationships because it allows for the aggregation of multiple related records. In scenarios where a single entity needs to link to several related entities, a Page List serves as a collection that can hold multiple instances of related objects. For instance, if you have a customer entity that can have several orders, a Page List would be the appropriate choice to store all the orders associated with that customer.

By using a Page List, applications can efficiently manage and manipulate collections of data, facilitating operations such as adding, removing, or iterating through the related records. This property type significantly enhances the ability to model real-world scenarios where one entity is directly related to multiple instances of another, thus providing a robust structure for data management and query.

In contrast, other options do not fulfill this purpose effectively. Single entities cannot manage multiple records, representing database tables is not the intended use of a Page List, and while it may not always be mandatory to set up relationships, its utility in managing '1-to-many' relationships is critical for ensuring data integrity and operational efficiency.
