Well, not exactly - just a way to separate access to data from everything else in the product.

Maybe a separate class that needs the connection as argument and that just returns the data I need in appropriate data structures by calling class methods.

 

class DataModel (object):

 

  def __init__ (self, conn):

    self.conn = conn

    self.sqlFetchSomething = SQL (.....)

 

  def fetchSomething (self):

    return self.sqlFetchSomething

 

This is really simple, but I think it gives the idea.

Obviously I'd like to perform various operation at the data level, for example return a list of lists for reportlab tables and so on.

 

TIA,
