While enterprise portals and web services give a new
face for this emerging paradigm, the skeleton of this "open enterprise" is provided
by an open IT infrastructure. The flesh is provided by emerging trends in Enterprise
Application Integration (EAI) practice.
Let us briefly visit a few selected issues faced by today's enterprises.
Multiple Systems
In a home business or in small scale ventures, we start up with systems and
applications in silos which cater to the entire setup. When the business grows,
we add more verticals, which are functionally separated entities within the same
organization. It goes without saying that, each of these verticals or LOB will have
their own systems. People ask why they have different systems. The answer is
because they are doing functionally different operations in an enterprise and hence
they need systems carrying out different functionality for them. For example, an HR
system will manage and maintain employee related data whereas the marketing
relations will use Customer Relationship Management (CRM) systems. These
systems may not be interconnected and hence impede information flow across LOBs.
