You can create 'Cubes' in Tableau. They're Tableau DataSource Extracts. You have to create an extract on your local machine and then publish it to the Tableau server.
You can refer these links for detailed information on how to create and publish extracts.
Hi Maneesh ,
So if I understand you correctly , the data extracts are equivalent to cubes in tableau ?
As in terms of slicing and dicing and the speed of loading etc ?
When your use extract in tableau it will give two option 1. Full refresh 2. Incremental Refresh.
In tableau you can do analysis and tableau is faster one.
That's correct. Speed of loading depends on the size of your extract. If you have an extract of 100M rows Tableau server does take sometime to process and fetch the data.
