The model was described in a 1987 paper (A Comparison of Commercial and Military Computer Security Policies) by David D. Clark and David R. Wilson.The paper develops the model as a way to formalize the notion of information integrity, especially as compared to the requirements for multilevel security (MLS) systems described in the Orange Book.
In business and IT development the term "systems modeling" has multiple meanings. It can relate to: the use of model to conceptualize and construct systems. the interdisciplinary study of the use of these models. the systems modeling, analysis, and design efforts. the systems modeling and simulation, such as system dynamics.
Computational model. A computational model uses computer programs to simulate and study complex systems [ 1] using an algorithmic or mechanistic approach and is widely used in a diverse range of fields spanning from physics, [ 2] engineering, [ 3] chemistry [ 4] and biology [ 5] to economics, psychology, cognitive science and computer science.
A system architecture primarily concentrates on the internal interfaces among the system's components or subsystems, and on the interface (s) between the system and its external environment, especially the user. (In the specific case of computer systems, this latter, special, interface is known as the computer human interface, AKA human ...
A diagram is a partial graphic representation of a system's model. The set of diagrams need not completely cover the model and deleting a diagram does not change the model. The model may also contain documentation that drives the model elements and diagrams (such as written use cases). UML diagrams represent two different views of a system ...
v. t. e. Systems theory is the transdisciplinary [ 1] study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems.
Computer simulation. Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict.
The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. [ 1] Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system.
