Systems architecture

System architecture called, derived from the definition of architecture in general ( = architecture ... ), discipline ( field of activity, task, management), which is focused on systems and the interacting components in them.

In addition to this activity -oriented understanding of system architecture is also similar to the general concept of architecture, including the structure and naming / presentation of systems and their components and is applied to any ' system concepts '.

IT

The system architecture is created according to the V -Modell XT in the context of system design and includes the decomposition of the system, the interface overview and the overarching data catalog ( data and system elements exchange ).

At the beginning of the system architecture works are identified by analysis of the overall system specification and other existing information architecture drivers and set evaluation criteria. Functional and non-functional requirements affect the design of the system architecture, which is documented in architectural views. This often UML diagrams are used. Finally, the system architecture is verified on the basis of the evaluation criteria.

Based on the system architecture, hardware and software architecture is determined during the detailed design.

Space travel

As a space system is called a spacecraft (eg Spacelab ), which is being developed by a responsible person. The overall system is then Spacelab plus space shuttle under the responsibility of NASA.

The system architecture of the spacecraft subsystems defined as data processing, navigation, etc. A subsystem in turn divided into units and components (eg solar sensor, computer, software, etc.).

Automotive

In the automotive sector, especially in development according to the norms Automotive SPICE and CMMI, the system architecture refers not only to hardware and software, but to the entire embedded system. This includes mechanical and mechatronic components such as switches, sensors, displays, or even the housing.
