What groups a set of related modules in OutSystems?

In OutSystems, the correct term for grouping a set of related modules is "Applications." This concept is central to the OutSystems platform, where applications serve as containers that group modules and associated resources, allowing for organized management and development of web and mobile applications. Each application can consist of multiple modules which can be reused across different applications, promoting modularity and code reuse.

Applications provide a high-level structure in the OutSystems environment, enabling developers to compartmentalize functionalities and manage dependencies between modules effectively. This organization also aids in deployment, versioning, and governance of the application as a whole.

The other terms listed do not serve the same purpose in the OutSystems architecture. Packages typically refer to collections of functionalities but are not used as a primary organizational structure for modules. Directories commonly refer to file system locations and are not specific to OutSystems' method of organizing application-related resources. Components can represent reusable functionalities within an application but do not encompass the broader organizational grouping of modules like applications do.
