(EAI) software, a component of the NetWeaver product
group
used to facilitate the exchange of information among a
company's
internal software and systems and those of external
parties.

providing
a common repository for interfaces. The central component
of SAP
XI is the SAP Integration Server, which facilitates interaction
between
diverse operating systems and applications across internal
and external networked
computer systems.
