Thank you @Hubert Dudek​ and @Prabakar Ammeappin​ 

​

but it's a bit weird because if i shut down my cluster I lose all my databases and tables

​

I create a new cluster and a new database

I shutting down/delete my cluster

When I create a new cluster the database is not existe anymore

​

Can you imagine, if somebody shutting down the cluster by accident or beat the idle time ... in this case you organisation lose all of databases and tables. If that's true, does not worth using the databases in databricks but in a other cloud
