4+1 Architectural View Model

The 4+1 Architectural View Model is a way to organize and describe a software system from different perspectives to ensure all aspects are covered. It includes four main views: the Logical View (how users interact with the system), the Development View (how the system is built), the Process View (how the system operates and handles tasks), and the Physical View (the hardware and network setup). The “+1” is the Scenarios or Use Cases, which connect all views by showing real-world examples of how the system works, helping stakeholders understand the complete picture.
