What is a pattern in OutSystems?

A pattern in OutSystems refers to a reusable design that can be applied to screens or modules. This concept is fundamental to OutSystems as it promotes consistency and efficiency in application development. By utilizing patterns, developers can ensure that common design elements and functionalities are implemented uniformly across various parts of the application.

This approach not only accelerates the development process—since elements do not need to be rewritten for every screen or module—but also enhances maintainability and readability of the code. For instance, a navigation pattern might dictate how users move through an app, maintaining a cohesive user experience and interface consistency.

The other options do not accurately describe a pattern in OutSystems. Documenting code, measuring application performance, and specific programming languages are all important components in the development process, but they do not capture the essence of what a pattern is within the OutSystems environment. Patterns specifically relate to design and usability, which are core to effective application development in OutSystems.
