Best Practices of using Oracle Business Intelligence
Use only logical links in the Business Model Mapping layer.
Rename the logical columns.
Remove unwanted objects to simplify the model
Use short names to save space in the references.
Use names corresponding to the organization, which is easily understandable for customers.
Do not use the same name with the name of the logical table in the BMM.
