Hi Nadya !

I use Enterprise Architect from sparx system http://www.sparxsystems.com.au/
My impressions are very good. Sentence below (from their web site) seems true to me.
"Enterprise Architect is a flexible, complete and powerful UML modeling tool for the Windows platform. Providing the competitive edge for system development, project management and business analysis, an object oriented CASE tool for the full development life-cycle - at a sensible price."
