Example of a high-level systems architecture for a computer. A system architecture is the conceptual model that defines the structure, behavior, and views of a system. [1] An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.
Example of a system context diagram. [1]A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2]
System integration is defined in engineering as the process of bringing together the component sub-systems into one system (an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality) and ensuring that the subsystems function together as a system, [1] and in information technology [2] as the process of linking together different computing ...
Software maps can express and combine information about software development, software quality, and system dynamics by mapping that information onto visual variables [7] of the tree map elements such as footprint size, height, color or texture. They can systematically be specified, automatically generated, and organized by templates.
The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
Data flow diagram with data storage, data flows, function and interface. A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system).
In the software development process, the top–down and bottom–up approaches play a key role. Top–down approaches emphasize planning and a complete understanding of the system. It is inherent that no coding can begin until a sufficient level of detail has been reached in the design of at least some part of the system.
A specification tree shows all specifications of a technical system under development in a hierarchical order. For a spacecraft system it has the following levels: System (requirements) specification - generated by customer System (design to) specification - generated by system responsible prime contractor
