, a composite application is a software application built by combining multiple existing functions into a new application. The technical concept can be compared to
mashups. However, composite applications use business sources (e.g., existing modules or even
Web services ) of information, while mashups usually rely on web-based, and often free, sources.
It is wrong to assume that composite applications are by definition part of a service-oriented architecture (SOA). Composite applications can be built using any technology or architecture.
A composite application consists of functionality drawn from several different sources. The components may be individual selected functions from within other applications, or entire systems whose outputs have been packaged as business functions, modules, or web services.
Composite applications often incorporate

Orchestration is the study or practice of writing music for an orchestra (or, more loosely, for any musical ensemble, such as a concert band) or of adapting music composed for another medium for an orchestra. Also called "instrumentation", orc ...
