BPM interacts through which layer?

Business Process Management (BPM) primarily interacts through the presentation layer. This layer is responsible for how information is displayed and how users interact with the application. In the context of BPM, the presentation layer is crucial because it allows users to visualize workflows, submit tasks, and monitor processes. It provides the necessary user interface for process orchestration, enabling stakeholders to engage with the processes effectively.

While there is a role for data access in BPM, it is not the primary layer for interaction. The data access layer is essential for retrieving and storing data, but it does not facilitate direct interaction with users in the way the presentation layer does. Instead, the data access layer supports the backend functionality that BPM relies on to present relevant information through the presentation layer.

Thus, when considering the specific context of user interaction and engagement with BPM solutions, the presentation layer is the predominant layer involved.
