Hi, I want to create a data warehouse using DLL scripts. So, I define the tables dimensions and table facts and I add relationships between them. Then, I define dimensions with their levels, hierarchies and attributes. Now, I'm wondering how to define a fact (I have to define it as a cube or a materialized view). I'm really confused. Please would you please help me? N.B: The generated scripts are executed using OWB 11g.
