Both UniVerse and Unidata are independent database products. Between 2000 and 2009 they were owned and marketed by IBM; in October 2009 they were sold to Rocket Sotftware. Both were created in the mid-1980s to try to take some of the market share of Prime INFORMATION.
The original vendor of UniVerse, VMark Software, was the original developer of DataStage, which is why the UniVerse database was selected as the engine layer. Another two reasons is that UniVerse and Unidata are not just databases but fully-fledged application development environments, and that an interface exists for exposing objects on a Windows client either as COM objects through an OLE server or through Java classes; these objects are the foundation for the DataStage client tools' communication with the server.
