Enterprise Software
Enterprise software, is software intended tosolve an enterprise problem (rather than a
departmental problem) and often written using
an Enterprise Software Architecture.
Due to the cost of building what is often
proprietary software, only large enterprises

core IT system of governing the enterprise and
the core of communication within the enterprise.
