We have several fairly large data warehouses that run on SQLServer. The performance is quite acceptable (provided the database is installed on a good enough SAN). SQLServer is still missing some nice features of Oracle (for example, no partitions -- need to use partition views, and read performance seems to degrade greatly in proportion with the number of partitions). Oracle's pricing, based on both cpu's + number of users, really discriminates against DW shops, which need powerful/multiple CPUs, but, for DSS's, may not have very many users.

Oracle OR simply otherwise limitations in general - OT There appear to be some very large OLTPs running sql server. Someone posted a link to a list of the largest databases in the world and several of them run on SQL Server. I have not used it, but I have been told it improved alot in the last two years. This might explain why oracle is lowering the prices for small to mid-level shops that threaten to go to sql server...=20 -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
