Title:
Affordable Enterprise Application Integration Strategy involving
Legacy Systems
Abstract: Early software systems (legacy systems) in areas
such as inventory control, human resources, sales automation and database
management were designed to run independently, with no interaction between
the systems. They were proprietary systems, custom built in the technology
of the day for specific needs. Tremendous changes are taking place
in the business world today because of the need to tap into enormous global
opportunities increasingly being created by Internet. Modern software systems
must conform to requirements, such as flexibility, adaptability, and continued
business process reengineering. Driven by these requirements, the migration
and integration of legacy systems towards new platforms and operating environments
provides an effective strategy for enterprises to maintain their competitive
edge. This paper presents a complete application integration strategy
for enterprises involving legacy systems. The paper is based on our earlier
work and conglomerates previous strategies with considerable architectural
changes and additional software components. We show that this approach provides
a significant reduction in total cost of ownership (TCO), while enhancing
organizational overall competency.
