What is Integrated Enterprise-Level Software?

"Integrated Enterprise-Level Software" is a very loose and subjective
description of a huge class of software. As worded, it is not a
specific piece of software, but a practically meaningless collection
of buzz-words.

You would do better to ask for more information from your boss in
order to ask a more specific question.

Good luck.

For the Gartner Group, enterprise software means high volume
transaction applications that manage the core business of an
enterprise.

Enterprise software means a computer application program designed for
and used by various enterprises including corporations, governmental
units and agencies, educational institutions, and similar
organizations. It does not include operating systems, entertainment,
personal or productivity software such as games, word processors,
spreadsheets and similar programs.

Integrated mean that multiple such applications are exchanging data
with each other for example, An accounting system is working with
inventory and production systems. These different systems are working
together because of integration.
