Here’s what one of our recent whiteboard sessions looked like: Write down every element of the system that you can think of, then use lines and arrows to show how they connect to each other. But the diagramming process doesn’t have to be complicated!

How to diagram system architecture for software products Here’s how we create system architecture diagrams. A good diagram also helps our clients and their stakeholders fully understand how our work interacts with their other existing systems, and gives them the information they need to do further enhancements in the future. Thoughtful documentation (like a system architecture diagram) is a way to show empathy for other coders by helping them quickly acclimate to complex projects. The “4+1” view model is rather “generic”: other notations and tools can be used, other design methods can be used, especially for the logical and process decompositions, but we have indicated the ones we have used with success.As part of our final project handoff to Tandem clients, we provide a diagram of the product’s architecture - a visual depiction of the various systems, platforms, and tools that work together to support a software product.Īt Tandem, documentation is more than just a best practice: it’s a way we demonstrate our values. The 4+1 view model is generic and is not restricted to any notation, tool or design method. This view is also known as the use case view.

They also serve as a starting point for tests of an architecture prototype. They are used to identify architectural elements and to illustrate and validate the architecture design. The scenarios describe sequences of interactions between objects and between processes.

Scenarios: The description of an architecture is illustrated using a small set of use cases, or scenarios, which become a fifth view.

UML diagrams used to represent the physical view include the deployment diagram. It is concerned with the topology of software components on the physical layer as well as the physical connections between these components.

Physical view: The physical view (aka the deployment view) depicts the system from a system engineer's point of view.

UML Diagrams used to represent the development view include the Package diagram and the Component diagram.

Development view: The development view (aka the implementation view) illustrates a system from a programmer's perspective and is concerned with software management.

UML diagrams to represent process view include the sequence diagram, communication diagram, activity diagram.

The process view addresses concurrency, distribution, integrator, performance, and scalability, etc.

Process view: The process view deals with the dynamic aspects of the system, explains the system processes and how they communicate, and focuses on the run time behavior of the system.

UML diagrams are used to represent the logical view, and include class diagrams, and state diagrams.

Logical view: The logical view is concerned with the functionality that the system provides to end-users.In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view.

The four views of the model are logical, development, process and physical view. The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers. View model in software architecture Illustration of the 4+1 Architectural View Model.Ĥ+1 is a view model used for 'describing the architecture of software-intensive systems, based on the use of multiple, concurrent views'.
