XML (Extensible Markup Language)

XML (Extensible Markup Language) is a specification language developed by the World Wide Web Consortium (W3C). XML is a language standard designed especially for Web documents, to allow programmers to create their own customized tags, thus enabling the definition, transmission, validation, and interpretation of data between applications and between organizations. XML is used extensively in STATISTICA Enterprise Server for communication in the client-server architecture; a special version of .XML  is PMML, which is used in STATISTICA (STATISTICA Data Miner) to store and share estimated (trained) models for deployment.
