Azure SQL and Oracle On-premise Sync or scheduled update

Hi,

We need to do a sync between SQL in Azure and Oracle on-premise. The sync can be a nightly sync or immediate sync. 

I did find an article to https://docs.microsoft.com/en-us/azure/sql-database/sql-database-get-started-sql-data-sync, but did not find a way out to perform the sync between SQL Azure and Oracle On-premise.

Appreciate your guidance to achieve it.

Thanks
