Hi Ravi,
The word "Dia" means "slide" or "visualization" in German. When the software switched from DOS to Windows 3.1, it was renamed from DIA to DIAdem to distinguish it as a Windows-based application. "Diadem" in Greek means "royal crown", and identical words with the same meaning exist in both German and English. So the product started as a way to visualize data and ended up positioned as "crowning" software.
