Have to work with Ingres DB right now, it has very uncomfortable GUI interface called Visual DBA. Is there any other interfaces which I can use to fork with this DB? need some think like SSMS, or may be there is some plugins which can be used in Visual DBA which can make work with it more user friendly.
Which version of Ingres? Ingres 10.0 and above have a tool called Director which is an alternative to Visual DBA. Some people also use a JDBC tool called Squirrel (see http://community.actian.com/wiki/Squirrel_Howto - use the Ingres 2006 configuration)
