The C4 model documents the architecture of a software system, by showing multiple points of view [5] that explain the decomposition of a system into containers and components, the relationship between these elements, and, where appropriate, the relation with its users. [3] The viewpoints are organized according to their hierarchical level: [2] [3]
Engineers run simulations with this system-level model to verify performance against requirements and to optimize tunable parameters. System-level simulation is used to test controllers connected to the simulated system instead of the real one. If the controller is a hardware controller like an ECU, the method is called hardware-in-the-loop. If ...
The first known prominent public usage of the term "Model-Based Systems Engineering" is a book by A. Wayne Wymore with the same name. [8] The MBSE term was also commonly used among the SysML Partners consortium during the formative years of their Systems Modeling Language (SysML) open source specification project during 2003-2005, so they could distinguish SysML from its parent language UML v2 ...
While in IEEE 1471, software architecture was about the architecture of "software-intensive systems", defined as "any system where software contributes essential influences to the design, construction, deployment, and evolution of the system as a whole", the 2011 edition goes a step further by including the ISO/IEC 15288 and ISO/IEC 12207 ...
The first tools to support MDE were the Computer-Aided Software Engineering tools developed in the 1980s. Companies like Integrated Development Environments (IDE – StP), Higher Order Software (now Hamilton Technologies, Inc., HTI), Cadre Technologies, Bachman Information Systems , and Logic Works (BP-Win and ER-Win) were pioneers in the field.
The four views of the model are logical, development, process, and physical view. In addition, selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence, the model contains 4+1 views: [1] Logical view: The logical view is concerned with the functionality that the system provides to end-users.
4+1 is a view model designed by Philippe Kruchten in 1995 for describing the architecture of software-intensive systems, based on the use of multiple, concurrent views. [17] The views are used to describe the system in the viewpoint of different stakeholders, such as end-users, developers and project managers.
[1] [2] The trend towards agile methods in software engineering is noticeable, [3] however the need for improved studies on the subject is also paramount. [4] [5] Also note that some of the methods listed might be newer or older or still in use or out-dated, and the research on software design methods is not new and on-going. [6] [7] [8] [9]
