Architekturstufen

Architekturstufen, often translated as architectural levels or layers, is a conceptual framework used in systems design and enterprise architecture to categorize and organize the various components and concerns of a complex system. This layered approach helps in understanding, planning, and managing the different aspects of a system at varying levels of abstraction.

Typically, these levels progress from the most abstract and strategic concerns to the most concrete and technical implementations. Common architectural levels include the Business Architecture level, which focuses on business strategy, goals, and processes. Below this is the Data Architecture level, concerned with how data is structured, stored, and managed. The Applications Architecture level deals with the individual software applications and their interactions. Finally, the Technology Architecture level describes the underlying hardware and software infrastructure, including networks, servers, and operating systems.

The purpose of using architectural levels is to provide a clear separation of concerns, allowing different stakeholders to focus on the aspects most relevant to them. It facilitates communication by providing a common language and structure for discussing system design. Furthermore, this layered model supports the identification of dependencies and impacts between different parts of the system, aiding in impact analysis and change management. By breaking down complexity into manageable levels, organizations can better align their IT systems with their business objectives and ensure a more robust and maintainable architecture.
