Which of the following describes the backend component of OutSystems architecture?

The backend component of OutSystems architecture is primarily responsible for managing data processing and business logic. This aspect of the architecture focuses on executing the core functions of the application, handling data manipulation, business rules, and other logic that underpin the application's operations.

In OutSystems, the backend is where the server logic resides, enabling the application to process requests, interact with databases, and perform computations necessary for delivering the required functionalities. This includes operations such as data storage, retrieval, and manipulation, as well as enforcing business rules that dictate how data can be accessed and used.

While other components like the user interface logic, external system integrations, and user access control are critical to the overall architecture, they do not primarily define the backend's role. The user interface logic is concerned with the presentation layer, external system integrations handle communication with other systems, and user access control focuses on security measures. All these elements work together, but the essence of the backend lies in its direct management of data processing and business logic, making it a pivotal aspect of OutSystems architecture.
