Design pattern

Gang of Four Design Patterns This section gives a high-level description of the twenty-three design patterns described by the Gang of Four. Each pattern description includes a link to a more detailed article describing the design pattern and including a UML diagram, template source code and a real-world example programmed using C#. Creational Patterns The first type of design pattern is the creational pattern. Creational patterns provide ways to instantiate single objects or groups of related objects

A design pattern must be represented in a structured manner so that it can be understood clearly and unambiguously. A good description enables the reader to grasp the essence of the pattern. It is expressed formally in terms of a pattern template. Several pattern template formats have been designed and used by researchers. The template used in this research work is based on the POSA book. Its elements and the description of each element are shown in Table 2.1. Element Meaning Name The pattern name

One Introduction What is a Design Pattern? A design pattern solves a problem within a given context. The solution that is offered by implementing a pattern results in a system design structure, which balances the concerns of the design problem in a manner most appropriate for the given context. In “Understanding and Using Patterns in Software Development”, Dirk Riehle and Heinz Zullighaven offer a rather nice definition of what a design pattern is: “A pattern is the abstraction from a concrete

Assignment #9 11/13/2017 Part 1: For this assignment, two design patterns will be covered: Observer and Visitor. Pattern #1, Observer: This design pattern provides a mechanism for one-to-many communication between an entity acting as an information source, called the “subject”, and any number of receiving entities, called “observers”. The pattern is also known by the the more descriptive name “publish-subscribe”. The advantage of this pattern is that the developer of the subject doesn’t need

Graphic design is very essential in our everyday life.  It is something that pulls in the advertisement and attracts our eyes for visual. It presents in everywhere that can be found in newspaper, magazines, books, internet sites, posters, products, arts. Heller and Vienne (p.15) reported that “most graphic design works, are not only using specialized graphics and multimedia software, to communicate ideas that inspire, messages, or beguile consumers.” In fact, graphic design is a complicate work

security pattern describes a specific security problem which arises in a given context and provides a sound, time-tested solution for the problem (Schumacher, Fernandez-Buglioni, Hybertson, Buschmann, & Sommerlad, 2006). Security design patterns are important tools for secure software engineering. In this section, we give a review of the literature on security design patterns. The survey covers patterns published at the PLoP (Pattern Languages of Programs) conferences, the hub of the patterns research

In this chapter, we will show step by step how to design architecture for a multimodal system based on complex event processing , we take an example of put that there system because its reference the base of multimodal system. 4.1 Define the problem – domain "Put That There” the bolt system is a voice and gesture interactive system implemented at the Architecture Machine Group at MIT. It allows a user to build and modify a graphical database on a large Format video Display. The Goal of the research

MVP Framework The MVP is derived from MVC software pattern, Pop and Altar 2014, that is useful for the structuring of user interfaces. The MVP design pattern separates the view from its presentation logic to allow each to be distinguished separately Qureshi and Sabir 2014, In MVP, the view goes on to become an ultra-thin component whose function is just to be able to offer a presentation to the user. The view captures and deals with the events increase by the user, though forwarding these directly
