Understanding the Oracle BI Applications Architecture
Previous releases of the Oracle BI Applications used Informatica PowerCenter as the embedded data integration engine, with individual data loading tasks being orchestrated into execution plans using another tool called the Data Warehouse Administration Console (DAC). Oracle BI Applications 11.1.1.7.1 instead uses Oracle Data Integrator 11g (11.1.1.7) to perform data loads, along with a number of Java-based applications that are deployed into managed servers within the Oracle Business Intelligence WebLogic domain. Figure 1 below shows the Oracle BI Applications logical product architecture, showing you how the usual WebLogic Server managed server deployed as part of an Oracle Business Intelligence BI domain extended to include new Oracle BI Applications-related Java applications, and a new managed server added that contains Oracle Data Integrator-related Java applications.
Oracle BI Applications 11.1.1.7.1 is set of packaged data extraction and loading routines designed to load a pre-built Oracle data warehouse, together with a set of dashboards, reports and other business metadata objects designed to provide customers with a quick-to-deploy, best-practice BI environment for Oracle's ERP and CRM applications. Whilst a full installation of Oracle Data Integrator is provided with Oracle BI Applications 11.1.1.7.1, its role is as an "embedded" data integration engine with administrators mainly interacting with it using web-based administration and configuration tools
