A "mashup" is a creative work that combines elements from different sources to create something new. This term is commonly used in music, where artists blend various songs or genres to produce a unique track. For example, a mashup might mix the vocals of one song with the instrumental of another, resulting in a fresh listening experience. In the digital world, mashups refer to web applications that integrate data or functionality from multiple sources. For instance, a mapping service that overlays real estate listings on a map is a mashup of geographic data and real estate information. These applications enhance user experience by providing diverse content in a single platform.
