" Logical models establish an interpretation relationship between formulae and structures. Models in Computer Science are largely organizational in that they show how data, a cooperation between agents, the process of creating a response to an external stimulus, an algorithm, or similar is structured . The emphasis of organization that is apparent in many models of computer science appears to be a consequence of either of the following: (1) complexity issues need to be dealt with such that a functional cohesion actually can be evaluated. (2) a domain of individuals or universe of discourse has to be established and the individuals within that domain are supposed to be capable of being distinguished from each other by means of their condition in that organization or particular handles available to a user of that model. III. The original of a model may itself be physical or conceptual. It may be so, independently of the consistency of the model. 1 18 Car Model Scale The model in the arts for example can be understood as an individual that functions as a proxy for certain aspects of a concept such as man, men, woman, child, etc. or as one of these under particular conditions. "

", the model is supposed to deviate from the original and as long as there is a good reason for that one doesn't worry. Software process models are in an idealizing reference mode to the actually realized software process. As the software process model describes how software shall be developed under ideal conditions there is no reason to be worried if one deviates from the model because the real conditions are not ideal. (4) constituting, i. e. , the original is constituted by the model and that makes devations from model to original imposible. On ontology is in constituting reference mode to the domain it constitutes. Car Model Rc The distinction between descriptive and prescriptive reference mode goes at least back to Wieringa, [2].
