OBIEE Administration tool is where all the back end process of reporting is done. This is the place where business logic, security etc is implemented on physical data. RPD is a file containing all the metadata of the logic/security etc is stored. It basically has 3 layers.
1) Physical Layer: This is where connection pools are created and physical tables are imported in to rpd from datawarehouse.
2) BMM layer: Here actual business logic is implemented on logical tables and it is the best practice to join tables using complex join in BMM layer.
3) Presentation layer: This layer is the visible to the user in the front end to create reports/requests. Security is implemented in this layer.
The flow is Physical>BMM>Presentation. We will discuss each layer in the coming posts.
