Legacy Extensions

Many companies face the challenge of adjusting their business to the realities of e-commerce in the most economical way possible. With their hard-earned legacy applications already firmly in place, many companies are opting for solutions that rely heavily upon Java technology because of its flexibility and extendability. Legacy applications can be extended through the use of Java technology in a way that adds functionality and saves money. With the rise of the Web, the market for legacy extension is increasing, freeing both traditional host-based (mainframe) and database-centric or client/server Enterprise Resource Planning (ERP) systems applications from the desktop and making them platform independent and Web-ready.

The benefits of extending conventional host-based applications from the proprietary desktops and networks include:
  • Big financial savings by cutting network and terminal costs.
  • Opportunities for electronic commerce using legacy databases.
  • More satisfied users who get an attractive graphical interface.
  • More integrated and efficient functionality.
SIPTECH has a unique expertise in this area by serving the clients in various domains.


Enterprise application integration (EAI) entails integrating applications and enterprise data sources so that they can easily share business processes and data without requiring significant changes to these existing applications and the data. EAI is best suited for heterogeneous environments whose applications and data do not all reside within the same environment. A company may have reached this point because of acquisitions or mergers with other companies in which they have been compelled to absorb some other company's systems into their own environment. They may have been trying to increase their capacity or to avoid replacing existing systems by patching their own internally developed systems or other purchased systems onto their core systems. Or, they may be supporting large numbers of users on distributed systems with a multitude of platforms. With the advent of the WWW, enterprise application integration has taken on a larger significance beyond that of merging application systems solely within an enterprise. The WWW has become a principal means of communication. An enterprise must be able to make its business data accessible to others, from internal employees to external partners, suppliers, and buyers.
