How EAI, ETL, and EII Work Together Integration across the enterprise is a long-standing goal of many organizations. EAI – a strategy or framework by which an organization centralizes and optimizes application integration
ETL – assimilates data from the legacy environment of heterogeneous technologies into the integrated, consistent world of the data warehouse or ODS, preparing it for consumption by the decision support processes
EII – framework for real-time integration of disparate data types from multiple sources inside and outside an enterprise, providing a universal data access layer, empowering developers to “pull” any kind of data from anywhere in the enterprise
