There's nothing special in Twisted for this.  If your database provides 
callback functionality, then you should be able to hook this up to your 
Twisted application somehow.  If you provide some more information about 
this, someone may be able to help you figure out how to do that.  If 
your database doesn't, then you either need a separate out-of-band 
notification when updates happen or you need to poll the database.
