Which entity type is a common model for specialization in Mendix?

The correct answer pertains to the concept of specialization in Mendix, where specific characteristics are inherited from a generic entity. In this case, FileDocument and Image are specialized entities that inherit properties from the generic Document entity. This specialization allows for enhanced organization of data, defining shared properties while also allowing unique attributes for FileDocuments and Images.

For instance, the Document entity might contain attributes applicable to all documents, such as a title or description, while FileDocument and Image can have additional attributes specific to their context, like file size for FileDocuments or resolution for Images. Utilizing this model enhances the reusability of entities and maintains a clean and organized data structure.

The other choices do not represent common models for specialization. User entities typically encompass system-wide user data without the same hierarchical specialization structure. Process entities are more about workflows and actions within applications, while Document entities are primarily a base for inheritance and do not reflect an advanced specialization model by themselves.
