In recent years, modern information systems have evolved in fundamental ways. As opposed to the traditional client-server architecture of data warehouses, modern informations systems consists of large volumes of distributed data sources, all connected by the Internet. Aside from being distributed, the data sources are also evolving, with their schemas updated frequently and asynchronously. Today's information systems are also heterogeneous. Beyond traditional databases, there is an emergence of novel sources of data. They include real-time streamed data, data services, sensor and radio frequency identification (RFID) readings.

近年来，现代信息系统已经从根本上得到了发展。与传统的数据仓库的客户机-服务器体系结构相反，现代信息系统由大量分布式数据源组成，所有数据源都通过Internet连接。 除了分布式之外，数据源也在不断发展，它们的模式经常异步更新。 今天的信息系统也是异构的。 除了传统的数据库之外，还出现了新的数据来源。 它们包括实时流数据、数据服务、传感器和射频识别（RFID）读数。
