I'm creating my first SQL Integration Package on my new SQL Server 2014. I will be pulling data from several IBM Informix databases hosted on Windows Server 2008 R2 machines. I was researching and found that OLE DB was faster than ADO.Net and ODBChttps://datatellblog.wordpress.com/2015/01/13/ssis-data-flows-ado-net-vs-ole-db-vs-odbc/
, but then I found the notification from Microsoft that OLE DB is depreciated as of SQL Server 2012, and I'm not even sure it can connect to Informix.
So, before I get much further, what is the recommended Connection type? I may be pulling 500,000 records.
