Answer Posted / Arpit Shukla
The 4+1 view model is a software architecture approach for system modeling. It consists of five views: 1) Logical (conceptual) view: describes the data, processes, and functions from the user's perspective. 2) Process view: represents how the system will perform its tasks, including interactions between components. 3) Development view: outlines the detailed design for each component in the process view. 4) Physical (external) view: explains the hardware, software, and interfaces required to implement the system. The "1" view, known as the usage scenario, describes how users will interact with the system from a functional and operational perspective.
