I am working on OBIEE and I remember from past few years I am hearing about Oracle Apps.Major Difference I notice between them is OBIEE is standard where you build your RPD and Reports/Dashboards from scratch based on requirements.Where as OBIEE Apps can have DAC,Informatica(Earlier as different component now it looks integrated), OBIEE RPD(Which has already tables and you can do customization) and Reports/Dashboards(Add Customization as per your requirements).So Oracle Apps has finance,HR,Procurement etc., modules and above components will be used by appropriate Industry.It's like end to end package for ETL and reports.Looks like 11.1.1.7 is latest version.
From few years hearing on Fusion Middleware,Oracle Fusion,E-Business suite 12.Are these related to Oracle Apps or different with extra features.
