Shannon Lowder shows us that you can write Biml to connect to an Oracle database as well:
Next, I wanted to build a package from Biml. A package that uses a connection to my Oracle instance. Defining connections to Oracle in Biml is similar to every other connection you’ve ever defined in Biml (lines 3-12). The difference here is the Provider. (line 10) I took the Provider attribute for my Oracle connection from the manual package I created in my previous test.
Simply right click on your Oracle connection in the package and choose properties. Then look at the Qualifier value. I take the whole value and copy and paste it into the Provider attribute in my BimlScript.
Once you have that defined, set up a Package with our two connections, and a data flow (lines 14 – 33). This script builds a simple data flow to move data from a single table on Oracle over to SQL Server. The only difference is, this time, the package is named Automatic, rather than Manual.
You could get as complex as you’d like in your example.
As far as Integration Services goes, Oracle is just another source or sink and as long as you have an appropriate driver, the flows work the same way as with any other database.
