What’s up with Mashup?
Mashup, in technological context, refers to a web application that makes use of a combination or mixture of data from two or more sources. This combination is then put together into one single device. A good example for this is the integration of cartographic data from Google Maps to real-estate facts, thus producing a different and fresh web service which is otherwise not provided by either or both sources. Consequently, the end-product of mashup is data or code that can be applied for software purposes.
Interestingly, mashup originated from a certain application in pop music, especially hip-hop in which a special song is created by combining two or more other songs.
