Recently, I created my first OBIEE report. To be honest, my biggest problem was to identify which tools to use. I might overlook the clues, but it took me quite some time before I could identify the important tools that I had to use. Finally, I understood that two important tools must be used:  the Oracle BI Administrator which allows us to create the objects that can be used to create the reports and  the internet page that must be used to modify the objects into a report.
Let us first discuss the Oracle BI Administrator.
This tool starts by inserting physical tables in the right columns. In my case, I inserted three tables: D1_LAND, D2_TIJD en F_FEITEN. I then dragged the tables to the business layer. There, I should be able to create the aggregations. After that I dragged the tables into the presentation layer.
The second tool is a page that links to the OBIEE environment. In my case www.van-maanen.com:7780/analytics. After logging on, I see the items in the presentation layer that I just created. Dragging the attributes that I would like to analyse yields:
This is my starting point for further analysis.
