At which layer does RPA interact with multiple applications?

RPA primarily interacts with multiple applications at the presentation layer. This layer is concerned with how users interact with the software applications, encompassing the graphical user interfaces (GUIs) and other visual components presented to users. Since RPA is designed to automate repetitive tasks performed by humans, it operates at the presentation layer by simulating the actions that a user would take on these applications, such as clicking buttons, entering data into fields, and reading information from screens.

The interaction at the presentation layer allows RPA tools to mimic user behavior without the need for direct access to the underlying application logic or data layers, making it versatile for various applications regardless of their internal architectures. By leveraging this layer, RPA can automate processes across different systems effectively, enabling seamless integration and workflow management across disparate applications.

In contrast, the object layer relates to how automation interacts with specific elements within the application in a more structured way, often involving object models or APIs, which may not be as widely applicable across all applications compared to presentation-level interactions. The data layer focuses on the information processed by applications but does not deal with user interactions directly. Therefore, the correct answer points to the layer where RPA's capability to work across multiple applications is most effectively realized.
