EII

(Enterprise Information Integration) Linking information within an enterprise. In most enterprises, information is stored in separate databases, data warehouses and applications. EII products make it possible to combine information from these different data sources on demand. They do this by establishing an intermediate data services layer that makes it possible to access the data in a standardized way, instead of having to interact directly with each separate back-end data source. Although EII is named after EAI, a class of technologies for linking applications, it follows a much more service-oriented model than traditional EAI products.
