Читать книгу IT Architecture from A to Z: Theoretical basis. First Edition - Vadim Aldzhanov - Страница 9

The earliest methodology and in my opinion the most complete and structured is the Zachman Framework. It was originally developed as an Information Systems architecture. The main idea is to provide the possibility of a consistent description of system’s individual aspects in coordination with all the rest. The Zachman model is used to describe the enterprise as a whole, so the proposed model can be generally used as a means for describing architectures of any complex production system. The main characteristics of this model are:

• Integrity of the enterprise;

• discussing complex issues using a relatively small number of non-technical concepts;

• applicability for solving problems, i.e. the ability to work with abstractions and entities, highlighting and isolating individual system parameters without losing the perception of the enterprise as a whole;

• Simplicity of description.

The advantages of the Zachman model over others are:

• It is easy to understand for both technical and non-technical experts;

• It has more detailed descriptions of architecture components;

• It can be applied to planning and better decision making;

• It has the most visible representation of the company’s components.

• It describes complex architecture using a small number of non-technical terms;

• It has independent tools for specific description;

• It can be used as a tool for describing architectures of any complex production system.
