What aspect does the development view focus on in the 4+1 methodology?

In the 4+1 architecture view model, the development view emphasizes the structure and design of the system from a developer's perspective. It focuses on the data mapping, the interactions within the software components, and how components are tested and verified.

By concentrating on data mapping and testing strategy, the development view helps ensure that individual components can be developed, integrated, and tested efficiently and effectively. It provides insights into how developers will build the application and how data flows between different parts of the system. This focus is crucial for addressing potential integration issues early in the development process and supporting quality assurance practices.

Other aspects, such as deployment strategies, user-specific needs, or business requirements, are addressed in different views of the 4+1 methodology. However, the development view specifically revolves around the technical aspects of software construction, making the focus on data mapping and testing strategy fundamentally important in providing a comprehensive architecture for developers.
