Diagram: In general, a model may refer to any abstraction that simplifies something for the sake of addressing a particular viewpoint. This definition specifically subclasses 'architectural models' to the subset of model descriptions that are represented as diagrams. Standards: Standards work when everyone knows them and everyone uses them ...
The C4 model is a lean graphical notation technique for modeling the architecture of software systems. [1] [2] It is based on a structural decomposition (a hierarchical tree structure) of a system into containers and components and relies on existing modelling techniques such as Unified Modeling Language (UML) or entity–relationship diagrams ...
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
Model-driven architecture (MDA) is a software design approach for the development of software systems.It provides a set of guidelines for the structuring of specifications, which are expressed as models.
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.
A model describes how units of computations, memories, and communications are organized. [1] The computational complexity of an algorithm can be measured given a model of computation. Using a model allows studying the performance of algorithms independently of the variations that are specific to particular implementations and specific technology.
It was described for the first time in 2002 in the book "Executable UML: A Foundation for Model-Driven Architecture". [1] The language "combines a subset of the UML (Unified Modeling Language) graphical notation with executable semantics and timing rules." [2] The Executable UML method is the successor to the Shlaer–Mellor method. [3]
A model conforms to its metamodel in the way that a computer program conforms to the grammar of the programming language in which it is written. Various types of metamodels include polynomial equations, neural networks, Kriging , etc. "Metamodeling" is the construction of a collection of "concepts" (things, terms, etc.) within a certain domain.
