Capturing application architecture in a design model

You have created the use case model that describes the requirements for the application and created an analysis model that identifies the application domain requirements and describes how the application will be structured. The next step in the development process is to build on the analysis model by exploring the architecture and implementation choices for the application.

The design phase takes the high-level model created during analysis and adds details to the actual implementation of the system. Using a variety of diagrams, including sequence, state machine, component, and deployment diagrams, you can create a model that describes, in detail, how the application is structured and how it will be implemented. Programming constructs and technologies, such as those used for persistence, distribution, security, and logging, are described. You can further refine the design model by applying design patterns that capture frequently used or complex structures and processes.

When you are ready to move to the implementation phase, the design model can be transformed to application code.
