For which type of entity does Mendix create a corresponding database table?

Mendix creates a corresponding database table for persistable entities because these entities are designed to store data that will be retained even after the application is closed or restarted. Persistable entities are fundamental to the app's data model, enabling data to be stored in the database, enabling long-term persistence and retrieval.

In contrast, transient entities are temporary and are used primarily for temporary data that does not need to be saved to a database, such as data that is only relevant during the lifetime of a session. Non-persistent entities follow a similar function, as they do not have dedicated tables in the database. They might be used for data that needs to be processed during the application's runtime but does not require ongoing storage. Association entities serve to define relationships between other entities and also do not generally have a dedicated table of their own in the database context. Thus, only persistable entities are associated with a physical representation in the database, leading to their corresponding table creation.
