I'm wondering if there are any existing software packages that can facilitate a link between Sybase and various other servers (Oracle, MS SQL Server 2000, DB2, etc.) and what the experience has been using these other packages. Specifically, I'm interested in finding out the ease of installation, learning curve, dependability, etc.
Apart from using ODBC there ain't any comprehensive middleware offering in the market that covers the full spectrum(in comparision with Direct Connect). You can use OLEDB in some instances, some others don't support native OLEDB connectivity to third-party databases(MS SQL 2000).
