iAnywhere 'Advantage'

[John Eiseman]

I'm strictly an FM-PRO  amateur/hobbyist, who has been using FM for  
about 10 years.  A co-worker is trying to educate me regarding  
Advantage Database Server, used in conjunction with Delphi and/or  
SQL.  I'm completely ignorant of these.  Can someone please explain,  
VERY briefly, the basic conceptual difference(s) between using FM  
versus ADS?  Most critical:  is there any reason why our company  
should NOT use FM Pro to manage several large databases, in favor of  
ADS or some other solution?  Is there any intrinsic deficiency with  
FM when compared to an ADS (Delphi/SQL) solution?  Thanks !!
