How robust/beefy is MS Sql Server compared to the big boys like Informix/Oracle/DB2? Is it a 'hundreds of terrabytes db' or 'millions(or tens of millions) of rows in the big tables' kind of solution a s/w architect would typically build upon? I'm more used to big boys I mentioned above with custom datablade data types that can cater to the large volume of real time data coming out of manufacturing process and the like.
