domain modeling

domain modeling The modeling of a part, or domain, of the external world with which a class of systems (possibly an individual system) will interact. The domain, which is often called the application domain or problem domain, contains the entities that are referred to by the information processed in a class of systems. A domain may include, for instance, natural phenomena, human artifacts, organizational functions, and information structures. Examples of domains are air traffic control, currency dealing, telecommunication switching, and supermarkets.

The purpose of a domain model is to enhance understanding of the structure and behavior of the domain, and of the requirements for systems that are to be embedded in it; a model could be said to provide the basic semantics for a class of systems. Domain modeling may have two benefits: (a) many individual systems may be tailored or instantiated from a single model; (b) the model may be more stable and longer lasting than individual systems. The more that either of those benefits can be obtained, the greater is the potential return on investment in the model. Achieving them, however, may mean that a domain model must be shared among a number of developers, and contributed to by a number of users; that may be difficult in the face of commercial competitive pressures.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
