JSP Model 2 is a complex design pattern used in the design of Java Web applications which separates the display of content from the logic used to obtain and manipulate the content. Since Model 2 drives a separation between logic and display, it is usually associated with the model–view–controller (MVC) paradigm.
A scenario has a goal, which is usually functional. A scenario describes one way that a system is used, or is envisaged to be used, in the context of an activity in a defined time-frame. The time-frame for a scenario could be (for example) a single transaction; a business operation; a day or other period; or the whole operational life of a ...
A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD) : A regular version of sequence diagram describes how the system operates, and every object within a system is described specifically.
For example, the best case for a simple linear search on a list occurs when the desired element is the first element of the list. Development and choice of algorithms is rarely based on best-case performance: most academic and commercial enterprises are more interested in improving average-case complexity and worst-case performance. Algorithms ...
Between the "good" and the "bad" case the language to represent the scenario is common: the use case diagrams are formally included in two modeling languages defined by the OMG: the Unified Modeling Language (UML) and the Systems Modeling Language (SysML), and this use of drawing the agents and misuse cases of the scenario explicitly helps ...
Scenery generators are commonly used in movies, animations and video games. For example, Industrial Light & Magic used E-on Vue to create the fictional environments for Pirates of the Caribbean: Dead Man's Chest. [citation needed] In such live-action cases, a 3D model of the generated environment is rendered and blended with live-action footage ...
A usage scenario for a piece of software; often used in the plural to suggest situations where a piece of software may be useful. A potential scenario in which a system receives an external request (such as user input) and responds to it. This article discusses the latter sense. (For more on the other sense, see for example user persona.)
In the previous example, the class Component is inherited by both the ConcreteComponent and the subclasses that descend from Decorator. The decorator pattern is an alternative to subclassing . Subclassing adds behavior at compile time , and the change affects all instances of the original class; decorating can provide new behavior at run-time ...
