[AccessD] Access - FoxPro - SQL2000

Hi List
 
Several time this year I've been asked to extract data a cash register type  
software and each ocassion the data is in Foxpro. Where does Foxpro fit into 
the  database market? Access is generally accepted as the entry level db and 
SQL 2000  is for the heavy duty db. Is there are market for Foxpro skills, is it 
 worth learning? or is it obsolete?
 
Comments most welcome
