Can applications contain multiple modules in OutSystems?

Applications in OutSystems can indeed contain multiple modules. This structure allows developers to better organize their code and maintain separation of concerns within the application. Each module can represent different functional areas, such as user management, business logic, or data access, contributing to a more manageable and modular architecture.

Having multiple modules also facilitates teamwork, as different developers can work on separate modules simultaneously without causing conflicts. Additionally, it aids in reusability since components within a module can be shared across different applications. The modular approach contributes to a cleaner architecture, making it easier to develop, update, and maintain applications over time.

The other options suggest limitations that do not align with OutSystems' capabilities. It is not required for modules to be public to exist within an application, nor is there a restriction that only one module can be active at a time. Multiple modules can coexist and be organized according to the needs of the overall application.
