A high-level programming language developed by Niklaus Wirth in the late 1960s. The language is named after Blaise Pascal, a seventeenth-century French mathematician who constructed one of the first mechanical adding machines. Pascal is best known for its affinity to structured programming techniques. The nature of the language forces programmers to design programs methodically and carefully. For this reason, it is a popular teaching language. Despite its success in academia, Pascal has had only modest success in the business world.
Parametric is a term used to describe a dimensionâs ability to change the shape of model geometry as soon as the dimension value is modified. Feature-based is a term used to describe the various components of a model. For example, a part can consists of various types of features such as holes, grooves, fillets, and chamfers. A âfeatureâ is the basic unit of a parametric solid model. Parametric modelling uses the computer to design objects or systems that model component attributes with real world behaviour. Parametric models use feature-based, solid and surface modelling design tools to manipulate the system attributes. One of the most important features of parametric modelling is that attributes that are interlinked automatically change their features.
Process models are processes of the same nature that are classified together into a model. Thus, a process model is a description of a process at the type level. Since the process model is at the type level, a process is an instantiation of it.The same process model is used repeatedly for the development of many applications and thus, has many instantiations.One possible use of a process model is to prescribe how things must/should/could be done in contrast to the process itself which is really what happens.A process model is roughly an anticipation of what the process will look like. What the process shall be will be determined during actual system development.ne possible use of a process model is to prescribe how things must/should/could be done in contrast to the process itself which is really what happens.
