Where can you edit the properties of an external entity?

Editing the properties of an external entity within the context of Mendix is typically done in the domain model of the app where that entity is defined. The domain model serves as the primary place for managing the structure of the application's data, including all entities that define how data is structured and how relationships between different entities are established.

When you need to adjust properties—such as attributes, data types, or constraints for an external entity—it is essential to do so within the domain model, as this reflects the design decisions that govern how the application interacts with that entity. The domain model allows for comprehensive editing and configuration of both internal and external entities, which is vital for ensuring the application's data architecture aligns with business needs.

The other options, while relevant in their own contexts, do not allow for the direct editing of external entity properties. The external entity’s settings panel primarily provides an overview or configuration settings rather than detailed editing capabilities. The database management tool focuses on database schemas and data manipulation rather than entity definitions. The admin console of Data Hub is geared towards managing resources and configured connections rather than modifying entity properties directly. Thus, the domain model is indeed the most appropriate location to edit an external entity's properties accurately and effectively.
