Information integration (II) is the merging of information from heterogeneous sources with differing conceptual, contextual and typographical representations.
Enterprise information integration (EII) supports a unified view of data and information for an entire organization. It is used in data mining and consolidation of data from unstructured or semi-structured resources. Typically, information integration refers to textual representations of knowledge but is sometimes applied to rich-media content.
Also has been referred to as Enterprise Content Integration (ECI).
