oo design: churned persistance settlement flush class

i am conceptualizing category record entries mail server. i have parsed record entries combined category hierarchy. i need save memory illustration disk. i need save churned destinations mysql hoop files. i am during detriment out repremand proceed settlement attention mechanism. hurdles are:

1. how pass persistence
   initialization information like
   filename, db tie parameters
   passed them. options i can
   think dizzy eg:

   
   
   

   1.1 constructor: becomes dizzy i
   add some-more persistence.

   
   
   

   1.2 method: object.mysql_params(" "),
   again boundary ugly




2. "correct" slight name each
   persistance mechanism: eg:
   object.save_mysql, object.save_file,
   or object.save (mysql) and
   object.save(file)

i am certain there settlement solve sole problem. i am controlling flush language, out any rails, ie pristine flush code. any thought many welcome.
