Software mashups and widgets
Mashup :
A mashup, in web development, is a web page, or web application, that uses and combines data, presentation or functionality from two or more sources to create new services. The term implies easy, fast integration, frequently using open application programming interfaces (API) and data sources to produce enriched results that were not necessarily the original reason for producing the raw source data.
The main characteristics of a mashup are combination, visualization, and aggregation. It is important to make existing data more useful, for personal and professional use. To be able to permanently access the data of other services, mashups are generally client applications or hosted online.
Mashups come in several varieties. Some mashups combine two or more media files (text, audio, video) to create new content. Web mashups combine two or more web applications to create a new service.
The name "mashup" is derived from the idea of combining data from two or more sources and displaying it with a unique look. However, newer mashups sometimes only use a single source of information. A good example of this is Twitter Spy, which only pulls data from Twitter. Developing a mashup can add richness to existing data or applications .
The best mashups are both visually appealing and either useful or, at least, entertaining to the point of needing to come with a warning label not to view at work if you want to get anything done.
