Executive Summary

The frequent development of e-commerce is making it ever more important for organizations to integrate their systems, which includes the legacy systems, to enable data to be transferred among applications. Four fundamental approaches to legacy integration are present which are Data-level integration, Application-interface integration, Method-level integration and User interface-level integration. Legacy applications continue to be present in several manufacturing or production functions as businesses have not found appropriate ERP applications which can be substituted for current software operations. Utilizing application server products to connect these legacy systems will present your company the capability to make this information accessible in real-time or to expand this data out to B2B channels and other external applications. Legacy systems store a huge amount of important business information, together with details of the customer; hence it is indispensable in case of companies to be capable of opening this data rapidly and without difficulty. Even though there are several advantages for system data level integration, it still has its limitations. It is being criticized as being very costly, rigid, and inaccessible and possesses lack of scalability and absence of ingenuousness. Further suitably experienced personnel are difficult to locate. After understanding the limitations, we have to be careful in adopting correct techniques for legal system integration. Nearly every company tackles the e-business and legacy systems integration by the use of some application integration instruments to access legacy data in a selective manner or activate back-end business dealings. These instruments tackle integration through the application of after-the-fact solutions which successfully differentiate recent systems from legacy settings for the long-term. This procedure presents restricted flexibility and impedes long-term, extensive up gradation alternatives to recent e-business systems and back-end settings. The intensities of integration thus must be propelled by the requirements of the business. The key is to match the integration category to the specific business requirement. The business argument for integrating legacy systems is really very potent, since it can unleash a lot of new opportunities for companies in case an appropriate technique of embracing the integration happens.
