At which layer does RPA interact with multiple applications?

The interaction of RPA with multiple applications primarily occurs at the presentation layer. This layer is responsible for managing the visual components of applications, where RPA bots can mimic human interactions by simulating mouse clicks, keyboard inputs, and other activities required to navigate and manipulate the user interface of applications across different environments.

In this layer, RPA tools work by recognizing UI elements and components of different applications, allowing the bots to perform tasks without needing direct access to the underlying code or database interaction. This is particularly beneficial for automating processes across various software platforms that may not have APIs or where integrating directly at a backend level is not feasible.

The other layers mentioned in the options, such as object and data layers, focus on different aspects of application integration. The object layer typically signifies a more structured method of interaction, dealing with specific objects in applications that expose their functionalities, while the data layer encompasses the management and exchange of data between applications. Therefore, these layers do not encompass the broader interaction capabilities of RPA across various applications, which is specifically characterized by the activities conducted at the presentation layer.
