Which best describes the primary function of the Domain Model?

The primary function of the Domain Model in Mendix is to manage data structures and relationships. The Domain Model serves as a representation of the application's data entities and the relationships between them, which is essential for defining how data is organized and accessed within the application.

In the context of software development, particularly in a low-code environment like Mendix, the Domain Model acts as a blueprint for the data layer. It allows developers to define entities, attributes, and their associations, which helps create a comprehensive understanding of the data flow and interactions. This structured approach is crucial for ensuring data integrity and consistency across the application.

By focusing on data structures and their relationships, the Domain Model enables efficient data management, fosters better application design, and supports business logic implementation. This alignment of data modeling with application requirements allows for a transparent and effective development process, simplifying maintenance and future enhancements.
