Recent practice has extended consideration to include behavioral, temporal and other dimensions of structure. Some authors limit the types of structure considered to be architectural for example, restricting themselves to functional and physical structure. The majority of interpretations of system architecture are based on the fairly intangible notion of structure (i.e. The SEBoK considers systems engineering to cover all aspects of the creation of a system, including system architecture. General Concepts and Principles Notion of Structure
1.4 Transition from System Requirements to Logical and Physical Architecture Models.1.3 Classification of Principles and Heuristics.1.2 Architecture Description of the System.It may also be applied to more than one system, in some cases forming the common structure, pattern, and set of requirements for classes or families of similar or related systems. It addresses the architectural principles, concepts, properties, and characteristics of the system-of-interest. It also focuses on high-level structure in systems and system elements. System Architecture is abstract, conceptualization-oriented, global, and focused to achieve the mission and life cycle concepts of the system.
The solution architecture has features, properties, and characteristics which satisfy, as far as possible, the problem or opportunity expressed by a set of system requirements (traceable to mission/business and stakeholder requirements) and life cycle concepts (e.g., operational, support) and which are implementable through technologies (e.g., mechanics, electronics, hydraulics, software, services, procedures, human activity). The purpose of system architecture architecture activities is to define a comprehensive solution based on principles, concepts, and properties logically related to and consistent with each other.
