Is a well developed concept in the data integration field and refers to the process of translating a user query expressed over a mediated schema into a query over the underlying data sources. The mediated schema itself is virtual; i.e., it does not contain any data. That is why queries that are posed by the user over that schema, have to be translated to queries over the real data sources.

Abstract
Modern enterprises across all spectra are increasingly adopting SOA-based data integration architectures to rapidly respond to transient data business needs. In this chapter, the authors analyze a new class of enterprise data integration application, called Data Mashup, in which data services are composed on the fly to answer new data business demands. The chapter reviews the different approaches to data mashup, discusses their limitations, and identifies the main requirements to data mashup. The authors next propose a declarative data mashup approach addressing the identified requirements. Finally, the chapter presents some research directions that must be followed in order for data mashup technology to mature.
