Gartner positions EII as a goal, not a technology. The goal is to achieve a state
where the various data assets of the enterprise are integrated to best meet the needs
of the business:
??? Delivering a timely and complete view of critical entities and events
??? Providing connectivity and accessibility to data across multiple platforms and
databases
??? Ensuring the consistency of data underpinning related applications

As such, the goal of EII differs little from the general goals of data integration,
which has been a focus of enterprises for the last three decades. (p. 1)
At its core, EII technology performs virtual data federation based on distributed
database queries (Friedman, 2004b, 2005).
However, the biggest problem is to know if the semantic of one item is the same in
all the databases. This is the added value of software like DB-Main (Hick & Hainaut,
2003), which produces a conceptual or semantic model of the organisational information.
