EAI is an integration framework, a middleware, which combines different technologies and services to establish smooth integration of applications and information systems such as ERP, SCM, CRM, HRM, and BI applications throughout the enterprise. It enables real-time data sharing and automation of business processes. EAI integrates multiple disparate business software without affecting the data structure. It enables rapid integration of different processes, systems, services, information, and devices to enhance the overall business performance. Growing data volumes, advances in technology, and growing demand for real-time data access are driving the need for EAI among enterprises, especially large enterprises.
