Sybase Inc.'s goals for PowerDesigner are nothing if not ambitious: a single modeling tool for tracking data definitions everywhere in an organization -- and Sybase doesn't just mean databases when it says data. Sybase PowerDesigner can also model data represented in XML schemas (including .WSDL files), process languages (BPEL and ebXML), object definition languages (Visual Basic, C#, Java, IDL-CORBA) and even .XLS files, among other choices.
