Curious, does Infomodler do reverse engineering the same as Erwin? Does it work with DB2, Oracle, Ingres, NetwareSql, SQL Server, SQLBase Sybase RDB Watcom AS/400 and Progress the same as Erwin? How about local databases like Clipper FoxPro, dBaseIII, dBaseIV Access and Paradox? Does it work directly with PowerBuilder? Does it sound like I like Erwin? -- gburnore@garys.arasmith.com ------------------------------------------------------------------------------- <-- Invisable Sig ------------------------------------------------------------------------------- | '۳''''''۳''''''''''''' Gary L.
