Today, organizations often want to exchange data quickly and precisely between computer systems using enterprise application integration technologies. Completed transactions are also often transferred to separate data warehouse and business rules systems with structures designed to support data for analysis. The industry de facto standard model for data integration platforms is the Common Warehouse Model (CWM). Data integration is often also solved as a data, rather than a metadata, problem, with the use of so called master data. ISO/IEC 11179 claims that it is a standard for metadata-driven exchange of data in an heterogeneous environment, based on exact definitions of data.
