OOHDM
OOHDM (Object-Oriented Hypermedia Design Method) is a method for the development of Web applications. It was one of the first methods to postulate the separation of concerns that defines its various models – requirements, conceptual, navigation, abstract interface and implementation. OOHDM, and its successor, SHDM (Semantic Hypermedia Design Method, which uses Semantic Web models) are supported by an open source, freely available environment, HyperDE.

Web Modeling
Web modeling (aka model-driven Web development) is a branch of Web engineering which addresses the specific issues related to design and development of large-scale Web applications. In particular, it focuses on the design notations and visual languages that can be used for the realization of robust, well-structured, usable and maintainable Web applications. Designing a data-intensive Web site amounts to specifying its characteristics in terms of various orthogonal abstractions. The main models that are involved in complex Web application design are: data structure, content composition, navigation paths, and presentation model. Several languages and notations have been devised for Web application modeling. Among them: * HDM - W2000 * RMM * OOHDM * the Interaction Flow Modeling Language (IFML), adopted by the Object Management Group (OMG) in March 2013 * ARANEUS * STRUDEL * TIRAMISU * WebML * Hera * UML Web Application Extension * UML-based Web Engineering UWE (UML-base ...

Web Application
A web application (or web app) is application software that is accessed using a web browser. Web applications are delivered on the World Wide Web to users with an active network connection. History In earlier computing models like client-server, the processing load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own pre-compiled client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the technical support, support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for ...

Web Engineering
The World Wide Web has become a major delivery platform for a variety of complex and sophisticated enterprise applications in several domains. In addition to their inherent multifaceted functionality, these Web applications exhibit complex behaviour and place some unique demands on their usability, performance, security, and ability to grow and evolve. However, a vast majority of these applications continue to be developed in an ad hoc way, contributing to problems of usability, maintainability, quality and reliability.Roger S Pressman, "What a Tangled Web we Weave," IEEE Software, Jan/Feb 2001, Vol. 18, No.1, pp 18-21 While Web development can benefit from established practices from other related disciplines, it has certain distinguishing characteristics that demand special considerations. In recent years, there have been developments towards addressing these considerations. Web engineering focuses on the methodologies, techniques, and tools that are the foundation of Web applicat ...

Software Architecture
Software architecture is the fundamental structure of a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. The ''architecture'' of a software system is a metaphor, analogous to the architecture of a building. It functions as a blueprint for the system and the developing project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved. Software architecture is about making fundamental structural choices that are costly to change once implemented. Software architecture choices include specific structural options from possibilities in the design of the software. For example, the systems that controlled the Space Shuttle launch vehicle had the requirement of being very fast and very reliable. Therefore, an appropriate real-time computing language would need to be chosen. Addition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
