It's for companies that have large data warehouse analytics systems. -- highlights: "Syncsort cites its main data integration competitors as being, no surprise, Ab Initio (their favorite choice to compare themselves to), Informatica (with PowerCenter), and IBM (with DataStage). Syncsort DMExpress runs on dedicated boxes. Unlike most of its competitors, this is not a real-time product it is a batch product that you schedule. Syncsort also told a story of an unnamed customer for whom Oracle utterly choked on joining 5 tables of 1 terabyte each. (27 days to run with clever workarounds.) DMExpress did the join in 6 hours." -- So, it's apparently so large and enterprisey that getting it to work right would take a large amount of effort, a sizable budget, and paid tech support.
