Organizations that successfully integrate their applications and data sources gain a competitive edge through enhanced efficiency and profitability. However, IT managers face significant challenges, including disparate legacy systems, varied hardware and networking technologies, and proprietary applications. Enterprise Application Integration (EAI) addresses this pressing need by enabling seamless communication between business processes and data across applications. This comprehensive examination of EAI covers its goals, approaches, and the technologies that support it, along with a roadmap for implementation.
