The input–process–output model. The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the ...
For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, representations of information, and maps, line graphs, bar charts, engineering blueprints, and architects' sketches are all examples of diagrams, whereas photographs and video are not".
Resources, Events, Agents. Resources, events, agents ( REA) is a model of how an accounting system can be re-engineered for the computer age. REA was originally proposed in 1982 by William E. McCarthy as a generalized accounting model, and contained the concepts of resources, events and agents (McCarthy 1982). REA is a popular model in teaching ...
N2 chart. N 2 chart example. [1] The N2 chart or N2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.
Example of a more complex EPC diagram (in German). An event-driven process chain ( EPC) is a type of flow chart for business process modeling. EPC can be used to configure enterprise resource planning execution, and for business process improvement. It can be used to control an autonomous workflow instance in work sharing.
Enterprise integration pattern. Genre. Non-fiction, Software development. Published. 10 October 2003. ISBN. 978-0321200686. Enterprise Integration Patterns is a book by Gregor Hohpe and Bobby Woolf and describes 65 patterns for the use of enterprise application integration and message-oriented middleware in the form of a pattern language .
Fork–join model. An illustration of the fork–join paradigm, in which three regions of the program permit parallel execution of the variously colored blocks. Sequential execution is displayed on the top, while its equivalent fork–join execution is on the bottom. In parallel computing, the fork–join model is a way of setting up and ...
Interaction design patterns are design patterns applied in the context human-computer interaction, describing common designs for graphical user interfaces. A design pattern is a formal way of documenting a solution to a common design problem. The idea was introduced by the architect Christopher Alexander for use in urban planning and building ...
