Portlets
Portlets are pluggable user interface software components that are managed and displayed in a web portal. A portlet responds to requests from a web client with and generates dynamic content. A portlet is managed by a portlet container. Description A portlet is a pluggable user interface software component that is managed and displayed in a web portal, for example an enterprise portal or a web CMS. A portlet can aggregate (integrate) and personalize content from different sources within a web page. A portlet responds to requests from a web client with and generates dynamic content. Portlets produce fragments of markup (HTML, XHTML, WML) that are aggregated into a portal. Hence, a portlet (or collection of portlets) resembles a web-based application that is hosted in a portal. Some examples of portlet applications are e-mail, weather reports, discussion forums, and news. Portlet containers A portlet is managed by a portlet container. A portlet container runs portlets, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Portal
A web portal is a specially designed website that brings information from diverse sources, like emails, online forums and search engines, together in a uniform way. Usually, each information source gets its dedicated area on the page for displaying information (a portlet); often, the user can configure which ones to display. Variants of portals include mashups and intranet dashboards for executives and managers. The extent to which content is displayed in a "uniform way" may depend on the intended user and the intended purpose, as well as the diversity of the content. Very often design emphasis is on a certain "metaphor" for configuring and customizing the presentation of the content (e.g., a dashboard or map) and the chosen implementation framework or code libraries. In addition, the role of the user in an organization may determine which content can be added to the portal or deleted from the portal configuration. A portal may use a search engine's application programming inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enterprise Portal
An enterprise portal, also known as an enterprise information portal (EIP), is a framework for integrating information, people and processes across organizational boundaries in a manner similar to the more general web portals. Enterprise portals provide a secure unified access point, often in the form of a web-based user interface, and are designed to aggregate and personalize information through application-specific portlets. One hallmark of enterprise portals is the de-centralized content contribution and content management, which keeps the information always updated. Another distinguishing characteristic is that they cater for customers, vendors and others beyond an organization's boundaries. This contrasts with a corporate portal which is structured for roles within an organization. History The mid-1990s saw the advent of public web portals. These sites provided a key set of features (e.g., news, e-mail, weather, stock quotes, and search) that were often presented in self- ...

Pluggable Look And Feel
Pluggable look and feel is a mechanism used in the Java Swing widget toolkit allowing to change the look and feel of the graphical user interface at runtime. Swing allows an application to specialize the look and feel of widgets by modifying the default (via runtime parameters), deriving from an existing one, by creating one from scratch, or, beginning with J2SE 5.0, by using the skinnable synth look and feel, which is configured with an XML property file. The look and feel can be changed at runtime. Architecture The corresponding API includes: * Hooks in Swing widgets to interact with their look and feel. Each widget defined in Swing can delegate its "painting" to its associated user interface classes called ''UI delegates''. * An API to manage existing look-and-feel definitions. This API allow to set the look and feel or switch from look and feels at runtime. * Another API to define a specific look and feel, or derive a look and feel from an existing one. Examples of look ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Applet
In computing, an applet is any small application that performs one specific task that runs within the scope of a dedicated widget engine or a larger program, often as a plug-in. The term is frequently used to refer to a Java applet, a program written in the Java programming language that is designed to be placed on a web page. Applets are typical examples of transient and auxiliary applications that do not monopolize the user's attention. Applets are not full-featured application programs, and are intended to be easily accessible. History The word ''applet'' was first used in 1990 in ''PC Magazine''. However, the concept of an applet, or more broadly a small interpreted program downloaded and executed by the user, dates at least to RFC 5 (1969) by Jeff Rulifson, which described the Decode-Encode Language, which was designed to allow remote use of the oN-Line System over ARPANET, by downloading small programs to enhance the interaction. This has been specifically credited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plug-in (computing)
In computing, a plug-in (also spelled plugin) or add-in (also addin, add-on, or addon) is a software component that extends the functionality of an existing software system without requiring the system to be software build, re-built. A plug-in software feature, feature is one way that a system can be customizable. Applications support plug-ins for a variety of reasons including: * Enable third-party developers to extend an application * Support easily adding new features * Reduce the size of an application by not loading unused features * Separate source code from an application because of incompatible software licenses Examples Examples of plug-in use for various categories of applications: * Digital audio workstations and audio editing software use audio plug-ins to generate, process or analyze sound. Ardour (software), Ardour, Audacity (audio editor), Audacity, Cubase, FL Studio, Logic Pro, Logic Pro X and Pro Tools are examples of such systems. * Email clients use plug-i ...

Application Programming Interface
An application programming interface (API) is a connection between computers or between computer programs. It is a type of software Interface (computing), interface, offering a service to other pieces of software. A document or standard that describes how to build such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that ...

News
News is information about current events. This may be provided through many different Media (communication), media: word of mouth, printing, Mail, postal systems, broadcasting, Telecommunications, electronic communication, or through the testimony of Witness, observers and witnesses to events. News is sometimes called "hard news" to differentiate it from soft media. Subject matters for news reports include war, government, politics, education, health, economy, business, fashion, sport, entertainment, and the Climate change, environment, as well as quirky or unusual events. Government proclamations, concerning Monarchy, royal ceremonies, laws, taxes, public health, and Crime, criminals, have been dubbed news since ancient times. Technology, Technological and Social change, social developments, often driven by government communication and espionage networks, have increased the speed with which news can spread, as well as influenced its content.

Weather Forecasting
Weather forecasting or weather prediction is the application of science and technology forecasting, to predict the conditions of the Earth's atmosphere, atmosphere for a given location and time. People have attempted to predict the weather informally for thousands of years and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere, land, and ocean and using meteorology to project how the atmosphere will change at a given place. Once calculated manually based mainly upon changes in atmospheric pressure, barometric pressure, current weather conditions, and sky conditions or cloud cover, weather forecasting now relies on numerical weather prediction, computer-based models that take many atmospheric factors into account. Human input is still required to pick the best possible model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and kn ...
