Hi

I am presently using Oracle Express on a UNIX box, in conjunction with an Oracle 8i database on another UNIX box (for producing OLAP cubes).

Can I replace the Oracle 8i database on the other UNIX box with a SQL Server database on an NT box? and...
1. Can Express communicate with SQL Server (I understand that Express has no ODBC drivers?) and how do I get it to do this?
2. My current setup takes about 5 hours to produce this OLAP cube - if the NT box has a similar spec in terms or CPU's and memory, which will be faster:
Oracle Express + Oracle 8i on seperate UNIX boxes
or
Oracle Express on UNIX box + SQL Server on NT box

Many thanks.
